5fabd2c311 Generalize the previous binary operator support and add a string concatenation 
operation.  This implements Regression/TableGen/strconcat.td.

f9e5ac8c9a 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.

7ae6895610 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.

86b5b7cf18 Don't sort the names before outputing the intrinsic name table. It causes a 
mismatch against the enum table.
This is a part of Sabre's master plan to drive me nuts with subtle bugs that
happens to only affect x86 be. :-)

723cb246c9 Tblgen doesn't like multiple SDNode<> definitions that map to the sameenum value. Split them into separate enums. 
Also, don't emit dynamic checks when we can compute them statically

de644c5e88 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
compile this:

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:
        movl 4(%esp), %eax
        movaps (%eax), %xmm0
        movmskps %xmm0, %eax
        ret

df3c89dd52 Temporary hack to enable more (store (op (load ...))) folding. This makes

71c62ae1f4 Don't generate silly matching code like this: 
if (N1.getOpcode() == ISD::ADD &&
     ...)
   if (... &&
       (N1.getNumOperands() == 1 || !isNonImmUse(N1.Val, N10.Val))) &&
       ...)

TableGen knows N1 must have more than one operand.
