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

d1ec11a850 Fixed another assert exposed by fuzzing. Now, the DisassembleVFPLdStMulFrm()

"ia" or "db") before calling ARM_AM::getAM5Opc(AMSubMode, unsigned char).

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.
