LLVM triple normalization is handling "unknown" and empty components
differently; for example given "x86_64-unknown-linux-gnu" and
"x86_64-linux-gnu" which should be equivalent, triple normalization
returns "x86_64-unknown-linux-gnu" and "x86_64--linux-gnu". autoconf's
config.sub returns "x86_64-unknown-linux-gnu" for both
"x86_64-linux-gnu" and "x86_64-unknown-linux-gnu". This changes the
triple normalization to behave the same way, replacing empty triple
components with "unknown".
This addresses PR37129.

match was the ld.elf_so that should be matched in a second step. Add one
of the ever-present-but-irrelevant-for-this-test arguments to the
pattern to force matching the right argument.

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.

Those used the old Big Endian support on ARM and don't need flags.
Refactor the logic in a separate common function, which also looks at
-march. Add corresponding logic for the Linux toolchain.

integrated assembler, libc++ and libgcc. Set emulation for ld for both
platforms for correct -m32 handling.

Don't bother with keeping the old support for x86_64 in 6.99.23+, just
use a single range. Update test cases for the always-on --eh-frame-hdr.

This covers all tests in tests/Driver and tests/Preprocessor, but there are some
failing tests in test/Sema that need looking into.
