Hao Xu 024e5fb4fa [CSA][codegen] Add BitcastElision Phase
Turbofan generates bitcast nodes like BitcastWordToTaggedSigned to
ensure the value types of definitions and uses are matched. These
nodes can be elided after MachineGraphVerifier verifying the graph.
This can avoid generating redundant instructions:

Before:
  xorl r15,r15
  cmpl [rdx+0xb],r15

After:
  cmpl [rdx+0xb],0x0
