(Re-apply patch after bug fixing)
This diff makes sure that the driver does not pass
-fomit-frame-pointer or -momit-leaf-frame-pointer to
the frontend when -pg is used. Currently, clang gives
an error if -fomit-frame-pointer is used in combination
with -pg, but -momit-leaf-frame-pointer was forgotten.
Also, disable frame pointer elimination in the frontend
when -pg is set.

Cross compiling from linux and OSX results in Error: Exec format.
This is because the linker is expecting ELF formated objects.
By passing the target we can explicitly tell the linker that
it should be linking COFF objects regardless of the host.

This allows us to construct Linux toolchains without a valid linker. This
is needed for example to build a CUDA device toolchain after r253385.

Currently clang requires several additional command
line options in order to enable new features needed
during CUDA compilation. This patch makes these
options default.
* Automatically include cuda_runtime.h if we've found
a valid CUDA installation.
* Disable automatic CUDA header inclusion during unit tests.
* Added test case for command line construction.
* Enabled target overloads and relaxed call checks that are
needed in order to include CUDA headers.
* Added CUDA-7.5 installation path to the CUDA installation search list.
* Define __CUDA__ macro to indicate CUDA compilation.

In order to compile a CUDA file clang must be able to find
include files for both both host and device.
This patch passes AuxToolchain to AddPreprocessingOptions and
uses it to add include paths for the opposite side of compilation.
We also must be able to find CUDA include files. If the driver
found CUDA installation, it adds appropriate include path
to CUDA headers. This can be disabled with '-nocudainc'.
- Added include paths for the opposite side of compilation.
- Added include paths to detected CUDA installation.
- Added -nocudainc to prevent adding CUDA include path.
- Added test cases to verify new functionality.

Clang needs to know target triple for both sides of compilation so that
preprocessor macros and target builtins from both sides are available.
This change augments Compilation class to carry information about
toolchains used during different CUDA compilation passes and refactors
BuildActions to use it when it constructs CUDA jobs.
Removed DeviceTriple from CudaHostAction/CudaDeviceAction as it's no
longer needed.

Last time, this caused two Windows buildbots and a single ARM buildbot to fail.
I XFAIL'd the failing test on win32,win64 machines in order to see if the ARM
buildbot complains again.

This currently changes the default toward the more historic -Av8/-Av9,
but as discussed with James Y Knight, consistency is for now more
important than figuring out which default CPU each OS should be using.

is not defined for 32bit mode, but __sparcv9 is. Pass down the correct
-target-cpu flags to the backend, so that instruction restrictions are
applied correctly. Pass down the correct -A flag when not using IAS.
The latter is limited to NetBSD targets in this commit.

The -meabi flag to control LLVM EABI version.
Without '-meabi' or with '-meabi default' imply LLVM triple default.
With '-meabi gnu' sets EABI GNU.
With '-meabi 4' or '-meabi 5' set EABI version 4 and 5 respectively.
A similar patch was introduced in LLVM.

This sets the mostly expected Darwin default ABI options for these two
platforms. Active changes from these defaults for watchOS are in a later patch.

This patch should add support for almost all command-line options and
driver tinkering necessary to produce a correct "clang -cc1"
invocation for watchOS and tvOS.

order to keep the buildbots clean.

This reverts commit r251695. Debug is meant to be done off tree, not use the buildbots
experiments. I'll help investigate this problem off trunk.

This should be a NFC for every toolchain other than mips-mti-linux (where we
print the list of directories searched for crt files). It will soon be
reverted once we hit the clang-cmake-armv7-a15-selfhost-neon buildbot.

The original commit in r249137 added the mips-mti-linux toolchain. However,
the newly added tests of that commit failed in few buildbots. This commit
re-applies the original changes but XFAILs the test file which caused
the buildbot failures. This will allow us to examine what's going wrong
without having to commit/revert large changes.

Previously, __weak was silently accepted and ignored in MRC mode.
That makes this a potentially source-breaking change that we have to
roll out cautiously. Accordingly, for the time being, actual support
for __weak references in MRC is experimental, and the compiler will
reject attempts to actually form such references. The intent is to
eventually enable the feature by default in all non-GC modes.
(It is, of course, incompatible with ObjC GC's interpretation of
__weak.)
If you like, you can enable this feature with
-Xclang -fobjc-weak
but like any -Xclang option, this option may be removed at any point,
e.g. if/when it is eventually enabled by default.
This patch also enables the use of the ARC __unsafe_unretained qualifier
in MRC. Unlike __weak, this is being enabled immediately. Since
variables are essentially __unsafe_unretained by default in MRC,
the only practical uses are (1) communication and (2) changing the
default behavior of by-value block capture.
As an implementation matter, this means that the ObjC ownership
qualifiers may appear in any ObjC language mode, and so this patch
removes a number of checks for getLangOpts().ObjCAutoRefCount
that were guarding the processing of these qualifiers. I don't
expect this to be a significant drain on performance; it may even
be faster to just check for these qualifiers directly on a type
(since it's probably in a register anyway) than to do N dependent
loads to grab the LangOptions.

In this patch, the file static method addProfileRT is
moved to be a virtual member function of base ToolChain class.
This allows derived toolchain to override the default behavior
easily and make it consistent with Darwin toolchain (a TODO was
added for this refactoring - now removed). A new helper method
is also introduced to test if instrumentation profile option
is turned on or not.
