Dan Gohman 24570836b2 Use PassManagerBase instead of FunctionPassManager for functions 
that merely add passes. This allows them to be used with either
FunctionPassManager or PassManager, or even with a custom new
kind of pass manager.

Dan Gohman d3a20c9e1e Give PassManager and FunctionPassManager a common base class, with 
add(Pass *) as a pure virtual member function. This will allow all
the various addPassesTo* functions in LLVM to avoid hard-coding what
type of PassManager is used.

Evan Cheng e88a625ecd When the register allocator runs out of registers, spill a physical register around the def's and use's of the interval being allocated to make it possible for the interval to target a register and spill it right away and restore a register for uses. This likely generates terrible code but is before than aborting.

Chris Lattner 1bd44363f2 Change the model for FP Stack return to use fp operands on the 
RET instruction instead of using FpSET_ST0_32.  This also generalizes
the code to handling returning of multiple FP results.

Dan Gohman d6819da453 Generalize ExpandIntToFP to handle the case where the operand is legal 
and it's the result that requires expansion. This code is a little confusing
because the TargetLoweringInfo tables for [US]INT_TO_FP use the operand type
(the integer type) rather than the result type.

Dale Johannesen 0fb187f81b Disable prolog code that aligns the stack when a 
local object of >16 byte alignment exists.  It does not
work and getting it to work is not trivial, as explained
in the comment.  This fixes all the remaining ppc32
failures in the struct-layout-1 part of the gcc testsuite.

(gcc does not support this either, and the only way to
get such an object is with __attribute__((aligned)) or
generic vectors; it can't be done in a standard-conforming
program, or with Altivec.  So I think disabling it is OK.)

Chris Lattner ce5f841bb5 fp_round's produced by getCopyFromParts should always be exact, because 
they are produced by calls (which are known exact) and by cross block copies
which are known to be produced by extends.

This improves:

define double @test2() {
	%tmp85 = call double asm sideeffect "fld0", "={st(0)}"()
	ret double %tmp85
}

from:

_test2:
	subl	$20, %esp
	# InlineAsm Start
	fld0
	# InlineAsm End
	fstpl	8(%esp)
	movsd	8(%esp), %xmm0
	movsd	%xmm0, (%esp)
	fldl	(%esp)
	addl	$20, %esp
	#FP_REG_KILL
	ret

to:

_test2:
	# InlineAsm Start
	fld0
	# InlineAsm End
	#FP_REG_KILL

Chris Lattner 322c826c9d Fix two problems in SelectionDAGLegalize::ExpandBUILD_VECTOR's handling 
of BUILD_VECTORS that only have two unique elements:

1. The previous code was nondeterminstic, because it walked a map in
   SDOperand order, which isn't determinstic.
2. The previous code didn't handle the case when one element was undef
   very well.  Now we ensure that the generated shuffle mask has the
   undef vector on the RHS (instead of potentially being on the LHS)
   and that any elements that refer to it are themselves undef.  This
   allows us to compile CodeGen/X86/vec_set-9.ll into:

_test3:
	movd	%rdi, %xmm0
	punpcklqdq	%xmm0, %xmm0
	ret

instead of:

_test3:

	#IMPLICIT_DEF %xmm0
	punpcklqdq	%xmm1, %xmm0

Scott Michel 944207423b This patch fixes a problem encountered by the CellSPU backend where variants 
were being pruned in patterns where a variable was used more than once, e.g.:

  (or (and R32C:$rA, R32C:$rC), (and R32C:$rB, (not R32C:$rC)))

In this example, $rC is used more than once and is actually significant to
instruction selection pattern matching when commuted variants are produced.
This patch scans the pattern's clauses and collects the variables, creating
a set of variables that are used more than once. TreePatternNode::isIsomorphicTo()
also understands that multiply-used variables are significant.

For x86, if sse2 is available, it's not a good idea since cvtss2sd is slower than a movsd load and it prevents load folding. On x87, it's important to shrink fp constant since fldt is very expensive.
