2a16652946 Introduce the "@llvm.dbg.value" debug intrinsic. 
The semantics of llvm.dbg.value are that starting from where it is executed, an offset into the specified user source variable is specified to get a new value.

An example:
  call void @llvm.dbg.value(metadata !{ i32 7 }, i64 0, metadata !2)
Here the user source variable associated with metadata #2 gets the value "i32 7" at offset 0.

d4427a6b63 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).

eee906f4f0 Dynamic stack realignment use of sp register as source/dest register 
in "bic sp, sp, #15" leads to unpredicatble behaviour in Thumb2 mode.
Emit the following code instead:
mov r4, sp
bic r4, r4, #15
mov sp, r4

5eba6ee969 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.
