Two Cleanups to generated C code:
...
1. Avoid printing *(&globalvariable), instead print globalvariable alone
as a special case.
2. Inline subexpressions into expressions as much as legal that preserves
execution characteristics of expressions. Now we get nice (but
over-parenthesized, oh well) things like:
ltmp_428_7 = spec__putc(((unsigned char )((bsBuff) >> 24)), (bsStream));
instead of five seperate instructions (bsBuff & bsStream are globals).
