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.

sys::cas_flag should be long on this platform, InterlockedAdd() is
defined only for the Itanium architecture (according to MSDN).

Emit the following code instead:
mov r4, sp
bic r4, r4, #15
mov sp, r4

because clang lowers nontrivial automatic struct/array inits to memcpy from
a global array.

Don't print "SrcLine"; just print the filename and line number, which
is obvious enough and more informative.

better.
