We need to use %icc and not %xcc for comparisons on 32-bit or smaller

Apparently, the "regType" and "regClass" used in the Sparc backend are not both
...
correct: empirically, "regType" is wrong for a number of registers. Thus, one
can only rely on the "regClass" to figure out what kind of register one is
dealing with.
This change switches to using only "regClass" and adds a few extra DEBUG() print
statements and a few clean-ups in comments and code, mostly minor.

(1) Major bug fix: DecomposeArrayRef() replaces its argument instr. and
...
deletes it, but we were merrily trying to fix the operands of that
instruction anyway! Instead, fix the replacement instruction.
(2) An Improvement: Check for and extract global values in all operands,
not just in known pointer operands. For example, they can occur in
call arguments, and probably other unforeseeable places as well.
This also eliminates the special-case handling of Load and Store.
