Gordon Henriksen 520e64c0c2 Fixing several transforms which would drop the collector attribute 
when copying functions.

Chris Lattner bea11173f5 update to llvm 2.0 syntax.

Chris Lattner ef1bbfc762 Don't break critical edges for single-bb loops, this helps with PR1877, though 
it is only a partial fix.  This change is noise for most programs, but
speeds up Shootout-C++/matrix by 20%, Ptrdist/ks by 24%, smg2000 by 8%,
hexxagon by 9%, bzip2 by 9% (not sure I trust this), ackerman by 13%, etc.

OTOH, it slows down Shootout/fib2 by 40% (I'll update PR1877 with this info).

Gordon Henriksen b969c5981b GC poses hazards to the inliner. Consider: 
define void @f() {
            ...
            call i32 @g()
            ...
    }

    define void @g() {
            ...
    }

The hazards are:

  - @f and @g have GC, but they differ GC. Inlining is invalid. This
    may never occur.
  - @f has no GC, but @g does. g's GC must be propagated to @f.

The other scenarios are safe:

  - @f and @g have the same GC.
  - @f and @g have no GC.
  - @g has no GC.

This patch adds inliner checks for the former two scenarios.

Gordon Henriksen fb56bde933 Noting and enforcing that GC intrinsics are valid only within a 
function with GC.

This will catch the error when the inliner inlines a function with
GC into a caller with no GC.

Chris Lattner 74b2ab59fd implement InstCombine/shift-trunc-shift.ll. This allows 
us to compile:
#include <math.h>
int t1(double d) { return signbit(d); }

into:

_t1:
	movd	%xmm0, %rax
	shrq	$63, %rax
	ret

instead of:

_t1:
	movd	%xmm0, %rax
	shrq	$32, %rax
	shrl	$31, %eax
	ret
