Michael van der Westhuizen: The attached patch add support for building against libc++abi and libcxxrt to CMake builds of libc++.

Usage (with the appropriate CC and CXX environment variables) is:
$ cmake -DLIBCXX_CXX_ABI=libcxxabi '-DLIBCXX_LIBCXXABI_INCLUDE_PATHS=/home/michael/libcxxabi/include' ../libcxx
and:
$ cmake -DLIBCXX_CXX_ABI=libcxxrt '-DLIBCXX_LIBCXXRT_INCLUDE_PATHS=/home/michael/libcxxrt/src' ../libcxx

AArch64 handles aggFct's return struct slightly differently, leading
to an extra memcpy. This test is fortunately only concerned about
volatile copies, so we can modify the grep text to filter it.

This should allow it to pass if the default triple is AArch64

Only some ABIs require the "signext" attribute on parameters. On most
platforms, however, it's a useful test so it's best not to limit it to some
random arbitrary platform.

This test was written to make sure *something* sane is generated, not
to test any ABI's signedness semantics.

This should allow the test to pass if AArch64 is the default target.

These instructions compare two floating point values and return an
integer true (-1) or false (0) value.

When compiling code generated by the Mesa GLSL frontend, the SET*_DX10
instructions save us four instructions for most branch decisions that
use floating-point comparisons.

This is a powerful tool when doing iterative refined matches,
where another match is started inside the match callback of the first
one; this allows for example to find out whether the node was in
the condition or body of its parent if-statement.

This removes Target and moves the functionality it had over to TargetInfo.

This also simplifies LinkerInput by removing the InputKind. This will be handled elsewhere.
