ARM: override cost function to re-enable ConstantHoisting (& fix it). At some point, ARM stopped getting any benefit from ConstantHoisting because the pass called a different variant of getIntImmCost. Reimplementing the correct variant revealed some problems, however: + ConstantHoisting was modifying switch statements. This is simply invalid, the cases must remain integer constants no matter the notional cost. + ConstantHoisting was mangling alloca instructions in the entry block. These should be handled by FrameLowering, so constants actually have a cost of 0. Worse, the resulting bitcasts meant they became dynamic allocas. rdar://25707382 llvm-svn: 266260 2016-04-14 07:08:27 +08:00			`if not 'ARM' in config.root.targets:`
