Normalize memcmp constant folding results.

to a constant. For example:
memcmp("foo", "foo", 3) -> 0
memcmp("hel", "foo", 3) -> 1

linked with. It currently just blindly uses the value returned from
the system memcmp as the folded constant.

(-1, 0, 1) so that we get consistent results across multiple platforms.

Add clang support of RTM from TSX
- New options '-mrtm'/'-mno-rtm' are added to enable/disable RTM feature
- Builtin macro '__RTM__' is defined if RTM feature is enabled
- RTM intrinsic header is added and introduces 3 new intrinsics, namely
'_xbegin', '_xend', and '_xabort'.
- 3 new builtins are added to keep compatible with gcc, namely
'__builtin_ia32_xbegin', '__builtin_ia32_xend', and '__builtin_ia32_xabort'.
- Test cases for pre-defined macro and new intrinsic codegen are added.

instcombine: Query target library information to gate libcall simplifications
Several of the simplifiers migrated from the simplify-libcalls pass to

information to gate the simplifications. This patch ensures that the

Add more functions to the target library information.
In the process of migrating optimizations from the simplify-libcalls pass
to the instcombine pass I noticed that a few functions are missing from
the target library information. These functions need to be available for
querying in the instcombine library call simplifiers. More functions will
probably be added in the future as more simplifiers are migrated to
instcombine.
