Transactional Memory was removed from the architecture in ISA v3.1. For
threads running in P8/P9 compatibility mode on P10 a synthetic TM
implementation is provided. In this implementation, tbegin. always sets
cr0 eq meaning the abort handler is always called. This is not an issue
as users of TM are expected to have a fallback non transactional way to
make forward progress in the abort handler. The TEXASR indicates if a
transaction failure is due to a synthetic implementation.
Some of the TM self tests need a non-degenerate TM implementation for
their testing to be meaningful so check for a synthetic implementation
and skip the test if so.

selftests/powerpc: Standardise TM calls2016-05-11T11:54:12ZRashmica Guptarashmicy@gmail.com2015-12-23T05:49:51Zurn:sha1:da3ddc3b5fea695f7b2fa89c4ca17dfd529293d2
Currently tbegin, tend etc are written as opcodes or asm instructions. So
standardise these to asm instructions.

Test the kernels signal generation code to ensure it can handle an
invalid stack pointer when transactional.
