Adjust how LLVM names are produced:
...
1. Always use % for local and @ for global.
2. Replace NameNeedsQuotes with QuoteNameIfNeeded so that any adjustments
to the name can be done in one pass.
3. Implement generation of hex escapes so we don't get "wonky" characters
in the output.

turn "putchar" calls into _IO_putc calls which is a lower-level interface.
This patch allows these calls to be executed by lli in interpreter mode.

Disable the (A == (B-A)) -> 2*A == B xform when the sub has multiple uses (in

this case, the xform introduces an extra operation). This compiles
PowerPC/compare-duplicate.ll into:
_test:
subf r2, r3, r4
cmplw cr0, r2, r3

instead of:
_test:

This is target independent of course.
