to force debug build and hopefully enable more precise warnings.
Static Analyzer is much more efficient when built in debug mode
(-UNDEBUG) so we advice users to enable it manually. This may be
inconvenient in case of large complex projects (think about Linux
distros e.g. Android or Tizen). This patch adds a flag to scan-build
which inserts -UNDEBUG automatically.

In addition to r251524: preserve the order the checkers were enabled/disabled to be deterministic.
Additionally return the number of arguments read by 'ProcessArgs' - for debug purpose.

A checker may be enabled/disabled multiple times via -enable-checker and -disable-checker scan-build arguments. Currently the conflicting and repetitive arguments are passed to the analyzer as is.
With this patch only the last enable/disable of a particular checker is accepted and passed to the analyzer.
This change is mostly done for the upcoming 'config for scan-build' patch when multiple inclusions/exclusions of a checker are expected to be more common.

The regex for -isystem matching is broken. -[D,I,Usystem] matches "-D", "-,",
"-I", "-U", "-s" "-y", etc. Besides that, "-isystem /foo" gets interpreted as
"-i" with a non-empty value "system" and thus the next "/foo" argument is not
read. This patch corrects the regex.
This fixes PR13237 <https://llvm.org/bugs/show_bug.cgi?id=13237>.

Update ccc-analyzer to forward both -Xclang and its following argument to the
the compiler driver. Previously we were dropping -Xclang and forwarding the
argument on its own if it matched other forwarding criteria. This caused the
argument to be interpreted as a driver rather than a frontend option.

- Eliminate 'No such file or directory at scan-build line ...' error if '$RealBin/bin/clang' or '$RealBin/clang' directory does not exist.
- Eliminate 'Use of uninitialized value $Clang in concatenation (.) or string at scan-build line ...' error if help is displayed while $Clang was not found.

Full list of changes:
- all scan-build command-line arguments are now kept in %Options hash.
- most of environment variables scan-build operates with are stored in %EnvVars hash.
- moved processing of command-line arguments to the ProcessArgs subroutine.

Don't derive the path_to_clang++ from the path_to_clang if the path_to_clang is really the path_to_clang++.

When interposing on a compiler doing cross-compilation, scan-build
does not infer the target triple needed to pass to clang for
doing static analysis. The --analyzer-target option allows one
to manually specify the target triple used during static analysis
(and only static analysis) for such cases.

Patch by Honggyu Kim
Summary:
This patch removes useless whitespace in File path in index.html
Previously, a File directory path is copied and pasted as below:
arch /arm /kernel /stacktrace.c
It just removes the whitespace between directories and makes the
copied string as below:
arch/arm/kernel/stacktrace.c
The output looks same in html format, but the copied directory path
can be pasted as it looks.

This reverts commit r236423 and its followup r236533, as indiscriminate
quoting makes for too much quoting (and clang doesn't like both '"-c"'
