Optimize suspend checks in optimizing compiler.
- Remove the ones added during graph build (they were added
for the baseline code generator).
- Emit them at loop back edges after phi moves, so that the test
can directly jump to the loop header.
- Fix x86 and x86_64 suspend check by using cmpw instead of cmpl.
