553ef1be94 Can't trust NodeDepth when checking for possibility of load folding creating 
a cycle. This increase the search space and will increase compile time (in
practice it appears to be small, e.g. 176.gcc goes from 62 sec to 65 sec)
that will be addressed later.

b0793f9741 Fixed a really ugly bug. The TableGen'd isel is not freeing the "inflight set" 
correctly. That is causing non-deterministic behavior (and possibly preventing
some load folding from happening).

d15531b430 Now that iPTR is a fully resolved type. We end up losing the type check for 
patterns that look like this:

def : Pat<(i32 (X86Wrapper tconstpool  :$dst)), (MOV32ri tconstpool  :$dst)>;

InsertOneTypeCheck should copy the type from the resolved pattern to the
unresolved one as long as there types are different.

f124b46b4f Final bugfix for PR724. GCC won't inline varargs functions, so use one to 
validate the prototype of intrinsic functions.  This prevents GCC from going
crazy and inlining too much stuff, eventually running out of memory.

c4d9b240b1 When emitting code for the verifier, instead of emitting each case statement 
independently, batch up checks so that identically typed intrinsics share
verifier code.  This dramatically reduces the size of the verifier function,
which should help avoid GCC running out of memory compiling Verifier.cpp.

5a1df389a6 Change approach so that we get codegen for free for intrinsics. With this, 
intrinsics that don't take pointer arguments now work.  For example, we can

int test3( __m128d *A) {
  return _mm_movemask_pd(*A);
}
int test4( __m128 *A) {
  return _mm_movemask_ps(*A);
}

to this:

_test3:
        movl 4(%esp), %eax
        movapd (%eax), %xmm0
        movmskpd %xmm0, %eax
        ret
_test4:

        movaps (%eax), %xmm0
        movmskps %xmm0, %eax
