[SystemZ] Rework processor feature definitions and add -mcpu=archX support This patch implements two changes: - Move processor feature definition into a new file SystemZFeatures.td, and provide explicit lists of supported and unsupported features for each level of the z/Architecture. This allows specifying unsupported features in the scheduler definition files for each processor. - Add optional aliases for the -mcpu processor names according to the level of the z/Architecture, for compatibility with other compilers on the platform. The supported aliases are: -mcpu=arch8 equals -mcpu=z10 -mcpu=arch9 equals -mcpu=z196 -mcpu=arch10 equals -mcpu=zEC12 -mcpu=arch11 equals -mcpu=z13 llvm-svn: 285577

[SystemZ] Support execution hint instructions This adds assembler support for the instructions provided by the execution-hint facility (NIAI and BP(R)P). This required adding support for the new relocation types for 12-bit and 24-bit PC- relative offsets used by the BP(R)P instructions. llvm-svn: 288031
