Thanks for the comments.
I will start working on these now and submit a new patch to Phabrictor once
I have the comments addressed.

Log:
Add Hardware Transactional Memory (HTM) Support
This patch adds Hardware Transaction Memory (HTM) support supported by
ISA 2.07
(POWER8). The intrinsic support is based on GCC one [1], with both
'PowerPC HTM
Low Level Built-in Functions' and 'PowerPC HTM High Level Inline
Functions'
implemented.
Along with builtins a new driver switch is added to enable/disable HTM
instruction support (-mhtm) and a header with common definitions (mostly
to
parse the TFHAR register value). The HTM switch also sets a preprocessor
builtin
HTM.
The HTM usage requires a recently newer kernel with PPC HTM enabled.
Tested on
powerpc64 and powerpc64le.
This is send along a llvm patch to enabled the builtins and option
switch.
