81da02b553 Make tail merging the default, except on powerPC. There was no prior art
for a target-dependent default with a command-line override; this way
should be generally usable.

9621921acb temporarily revert reid's asmwriter patch, it is missing the asmparser piece
that decodes the escape sequences, thus breaking all cases that use them.

This fixes test/Assembler/2007-05-21-Escape.ll

922d0bcf8b 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.

2ad913b342 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
        bne cr0, LBB1_2 ;F

instead of:

_test:
        slwi r2, r3, 1
        subf r3, r3, r4
        cmplw cr0, r4, r2
        bne cr0, LBB1_2 ;F

This is target independent of course.
