Jakob Stoklund Olesen 9f946a24d9 Fix some scavenger performance issues. ... - Don't call malloc+free in the very hot forward(). - Don't call isTiedToDefOperand(). - Don't create BitVector temporaries. - Merge DeadRegs into KillRegs. - Eliminate the early clobber checks, they were irrelevant to scavenging. - Remove unnecessary code from -Asserts builds. This speeds up ARM PEI by 3.4x and overall llc -O0 codegen time by 11%. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@149189 91177308-0d34-0410-b5e6-96231b3b80d8		2012-01-29 01:29:28 +00:00
