de0ade4939 Cast to (uint64_t) instead of relying on the "ul" suffix.

bde0bb5f88 building on the new CallGraphSCC abstraction, teach CallGraphSCCPassManager 
to keep the node entries in scc_iterator up to date instead of dangling as
the SCC mutates.

This is a really terrible problem which was causing -g to affect codegen 
because it would permute the memory image of the compiler process.

Thanks to Dale for expertly hunting it down.

2decb22222 introduce a new CallGraphSCC class, and pass it around 
to CallGraphSCCPass's instead of passing around a
std::vector<CallGraphNode*>.  No functionality change,
but now we have a much tidier interface.

c7b65914e0 Fixed a bug in DisassembleN1RegModImmFrm() where a break stmt was missing for a 
case.  Also, the 0xFF hex literal involved in the shift for ESize64 should be
suffixed "ul" to preserve the shift result.

Implemented printHex*ImmOperand() by copying from ARMAsmPrinter.cpp and added a
test case for DisassembleN1RegModImmFrm()/printHex64ImmOperand().

47639fc5be The JIT calls TidyLandingPads to tidy up the landing pads. However, because the 
JIT doesn't use the MC back-end asm printer to emit labels that it uses, the
section for the MCSymbol is never set. And thus the MCSymbol for the EH label
isn't marked as "defined". Because of that, TidyLandingPads removes the needed
landing pads from the JIT output. This breaks EH for every JIT program.

This is a work-around for this limitation. We pass in the label locations
map. If the label has a non-zero value, then it was "emitted" by the JIT and
TidyLandingPads shouldn't remove that label.

A nicer solution would be to mark the MCSymbol as "used" by the JIT and not rely
upon the section being set to determine if it's defined or not.

64b7bf71e8 Adding support for dag combiner to promote operations for profit. This requires target specific queries. For example, x86 should promote i16 to i32 when it does not impact load folding. 
x86 support is off by default. It can be enabled with -promote-16bit.

Work in progress.

626f3d7a57 Avoid sinking machine instructions into a loop. 
MachineLoopInfo is already available when MachineSinking runs, so the check is
free.

There is no test case because it would require a critical edge into a loop, and
CodeGenPrepare splits those. This check is just to be extra careful.

165dac08d1 rotate CallInst operands, i.e. move callee to the back 
of the operand array

the motivation for this patch are laid out in my mail to llvm-commits:
more efficient access to operands and callee, faster callgraph-construction,
smaller compiler binary

e6987587d6 enhance the load/store narrowing optimization to handle a 
tokenfactor in between the load/store.  This allows us to 
optimize test7 into:

_test7:                                 ## @test7
## BB#0:                                ## %entry
	movl	(%rdx), %eax
                                        ## kill: SIL<def> ESI<kill>
	movb	%sil, 5(%rdi)
	ret

instead of:

_test7:                                 ## @test7
## BB#0:                                ## %entry
	movl	4(%esp), %ecx
	movl	$-65281, %eax           ## imm = 0xFFFFFFFFFFFF00FF
	andl	4(%ecx), %eax
	movzbl	8(%esp), %edx
	shll	$8, %edx
	addl	%eax, %edx
	movl	12(%esp), %eax
	movl	(%eax), %eax
	movl	%edx, 4(%ecx)
	ret

6dc868581b teach codegen to turn trunc(zextload) into load when possible. 
This doesn't occur much at all, it only seems to formed in the case
when the trunc optimization kicks in due to phase ordering.  In that
case it is saves a few bytes on x86-32.

efcddc3325 add a simple dag combine to replace trivial shl+lshr with

2392ae7d73 Implement rdar://7860110 (also in target/readme.txt) narrowing 
a load/or/and/store sequence into a narrower store when it is
safe.  Daniel tells me that clang will start producing this sort
of thing with bitfields, and this does  trigger a few dozen times
on 176.gcc produced by llvm-gcc even now.

This compiles code like CodeGen/X86/2009-05-28-DAGCombineCrash.ll 
into:

        movl    %eax, 36(%rdi)

instead of:

        movl    $4294967295, %eax       ## imm = 0xFFFFFFFF
        andq    32(%rdi), %rax
        shlq    $32, %rcx
        addq    %rax, %rcx
        movq    %rcx, 32(%rdi)

and each of the testcases into a single store.  Each of them used
to compile into craziness like this:

_test4:
	movl	$65535, %eax            ## imm = 0xFFFF
	andl	(%rdi), %eax
	shll	$16, %esi
	addl	%eax, %esi
	movl	%esi, (%rdi)
	ret

d907d2566a Fixed another assert exposed by fuzzing. The utility function getRegisterEnum() 
was asserting because the (RegClass, RegNum) combination doesn't make sense from
an encoding point of view.

Since getRegisterEnum() is used all over the place, to change the code to check
for encoding error after each call would not only bloat the code, but also make
it less readable.  An Err flag is added to the ARMBasicMCBuilder where a client
can set a non-zero value to indicate some kind of error condition while building
up the MCInst.  ARMBasicMCBuilder::BuildIt() checks this flag and returns false
if a non-zero value is detected.
