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