Only enable LiveRangeShrink for x86. Summary: Moving LiveRangeShrink to x86 as this pass is mostly useful for archtectures with great register pressure.

Add LiveRangeShrink pass to shrink live range within BB. Summary: LiveRangeShrink pass moves instruction right after the definition with the same BB if the instruction and its operands all have more than one use. This pass is inexpensive and guarantees optimal live-range within BB.

[CodeGen] Always use `printReg` to print registers in both MIR and debug output As part of the unification of the debug format and the MIR format, always use `printReg` to print all kinds of registers. Updated the tests using '_' instead of '%noreg' until we decide which one we want to be the default one. Differential Revision: https://reviews.llvm.org/D40421 llvm-svn: 319445
