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

shlq $32, %rcx
addq %rax, %rcx
movq %rcx, 32(%rdi)

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.

Fixed a nasty layering violation in the edis source
...
code. It used to #include the enhanced disassembly
information for the targets it supported straight
out of lib/Target/{X86,ARM,...} but now it uses a
new interface provided by MCDisassembler, and (so
far) implemented by X86 and ARM.
Also removed hacky #define-controlled initialization
of targets in edis. If clients only want edis to
initialize a limited set of targets, they can set
--enable-targets on the configure command line.

Teach MachineSinking to handle easy critical edges.
...
Sometimes it is desirable to sink instructions along a critical edge:
x = ...
if (a && b) ...
else use(x);
The 'a && b' condition creates a critical edge to the else block, but we still
want to sink the computation of x into the block. The else block is dominated by
the parent block, so we are not pushing instructions into new code paths.
