bcc2e45840 Fixes the Atomic implementation if compiled by MSVC compiler.
sys::cas_flag should be long on this platform, InterlockedAdd() is
defined only for the Itanium architecture (according to MSDN).

7cca606aaa Dynamic stack realignment use of sp register as source/dest register

mov sp, r4

faf815b938 Handle forwarding local memsets to loads. For example, we optimize this:
short x(short *A) {
  memset(A, 1, sizeof(*A)*100);
  return A[42];
}

to 'return 257' instead of doing the load.
