Avoid sinking machine instructions into a loop.

MachineLoopInfo is already available when MachineSinking runs, so the check is

There is no test case because it would require a critical edge into a loop, and

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.
