[SystemZ] Be more careful about inverting CC masks
System z branches have a mask to select which of the 4 CC values should
cause the branch to be taken. We can invert a branch by inverting the mask.
However, not all instructions can produce all 4 CC values, so inverting
the branch like this can lead to some oddities. For example, integer
comparisons only produce a CC of 0 (equal), 1 (less) or 2 (greater).
If an integer EQ is reversed to NE before instruction selection,
the branch will test for 1 or 2. If instead the branch is reversed
after instruction selection (by inverting the mask), it will test for
1, 2 or 3. Both are correct, but the second isn't really canonical.
This patch therefore keeps track of which CC values are possible
and uses this when inverting a mask.
Although this is mostly cosmestic, it fixes undefined behavior
for the CIJNLH in branch-08.ll. Another fix would have been
to mask out bit 0 when generating the fused compare and branch,
but the point of this patch is that we shouldn't need to do that
in the first place.
The patch also makes it easier to reuse CC results from other instructions.

[SystemZ] Support transactional execution on zEC12
The zEC12 provides the transactional-execution facility. This is exposed
to users via a set of builtin routines on other compilers. This patch
adds LLVM support to enable those builtins. In partciular, the patch:
- adds the transactional-execution and processor-assist facilities
- adds MC support for all instructions provided by those facilities
- adds LLVM intrinsics for those instructions and hooks them up for CodeGen
- adds CodeGen support to optimize CC return value checking
Since this is first use of target-specific intrinsics on the platform,
the patch creates the include/llvm/IR/IntrinsicsSystemZ.td file and
hooks it up in Intrinsics.td. I've also changed Triple::getArchTypePrefix
to return "s390" instead of "systemz", since the naming convention for
GCC intrinsics uses "s390" on the platform, and it neemed more straight-
forward to use the same convention for LLVM IR intrinsics.
An associated clang patch makes the intrinsics (and command line switches)
available at the source-language level.
For reference, the transactional-execution instructions are documented
in the z/Architecture Principles of Operation for the zEC12:
http://publibfp.boulder.ibm.com/cgi-bin/bookmgr/download/DZ9ZR009.pdf
The associated builtins are documented in the GCC manual:
http://gcc.gnu.org/onlinedocs/gcc/S_002f390-System-z-Built-in-Functions.html

[SystemZ] Support transactional execution on zEC12
The zEC12 provides the transactional-execution facility. This is exposed
to users via a set of builtin routines on other compilers. This patch
adds LLVM support to enable those builtins. In partciular, the patch:
- adds the transactional-execution and processor-assist facilities
- adds MC support for all instructions provided by those facilities
- adds LLVM intrinsics for those instructions and hooks them up for CodeGen
- adds CodeGen support to optimize CC return value checking
Since this is first use of target-specific intrinsics on the platform,
the patch creates the include/llvm/IR/IntrinsicsSystemZ.td file and
hooks it up in Intrinsics.td. I've also changed Triple::getArchTypePrefix
to return "s390" instead of "systemz", since the naming convention for
GCC intrinsics uses "s390" on the platform, and it neemed more straight-
forward to use the same convention for LLVM IR intrinsics.
An associated clang patch makes the intrinsics (and command line switches)
available at the source-language level.
For reference, the transactional-execution instructions are documented
in the z/Architecture Principles of Operation for the zEC12:
http://publibfp.boulder.ibm.com/cgi-bin/bookmgr/download/DZ9ZR009.pdf
The associated builtins are documented in the GCC manual:
http://gcc.gnu.org/onlinedocs/gcc/S_002f390-System-z-Built-in-Functions.html
