Bill Wendling 66470d02c3 Move option to enable machine LICM into LLVMTargetMachine.cpp.

Chris Lattner f3edc09f9b Add a really quick hack at a machine code sinking pass, enabled with --enable-sinking. 
It is missing validity checks, so it is known broken.  However, it is powerful enough
to compile this contrived code:

void test1(int C, double A, double B, double *P) {
  double Tmp = A*A+B*B;
  *P = C ? Tmp : A;
}

into:

_test1:
	movsd	8(%esp), %xmm0
	cmpl	$0, 4(%esp)
	je	LBB1_2	# entry
LBB1_1:	# entry
	movsd	16(%esp), %xmm1
	mulsd	%xmm1, %xmm1
	mulsd	%xmm0, %xmm0
	addsd	%xmm1, %xmm0
LBB1_2:	# entry
	movl	24(%esp), %eax
	movsd	%xmm0, (%eax)
	ret

instead of:

_test1:
	movsd	16(%esp), %xmm0
	mulsd	%xmm0, %xmm0
	movsd	8(%esp), %xmm1
	movapd	%xmm1, %xmm2
	mulsd	%xmm2, %xmm2
	addsd	%xmm0, %xmm2
	cmpl	$0, 4(%esp)
	je	LBB1_2	# entry
LBB1_1:	# entry
	movapd	%xmm2, %xmm1
LBB1_2:	# entry
	movl	24(%esp), %eax
	movsd	%xmm1, (%eax)
	ret

woo.

Bill Wendling ddc77f8e4c Remove the default else. This was ending in code that looked like this: 
if (!strcmp(Target, "x86")) {
  // ...

Ted Kremenek 739d350369 renamed class "GRCP" (Graph Reachabilty Constant Propagation) to 
"GREngine" (Graph Reachability Engine).  The idea is to provide a separation
of concerns between the constant prop. details and the core analysis engine.

Ted Kremenek 0044908de0 Initial checking of GRConstantPropagation.cpp, which implements a constant 
propagation analysis via graph reachability. This analysis (which is incomplete)
will be the basis for later developments on the core engine for path-sensitive
analysis analysis.

Chris Lattner f391883670 don't hoist FP additions into unconditional adds + selects. This

Chris Lattner 76719ba5f1 Remove the function attr cache for intrinsics. This does not maintain the 
refcount on these correctly, and can end up referring to deleted 
attributes.  This fixes PR1881.

Duncan Sands a7f7ac7072 An example for which the TYPE_SIZE was being set from 
the initial value, while the type fields were not (this
is a qualified union type, so not all fields are always
present).  This resulted in the size of the corresponding
LLVM type being larger than the gcc TYPE_SIZE.
