Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

Rewrite the branch selector to be correct in the face of large functions.
...
The algorithm it used before wasn't 100% correct, we now use an iterative
expansion model. This fixes assembler errors when compiling 403.gcc with
tail merging enabled.
Change the way the branch selector works overall: Now, the isel generates
PPC::BCC instructions (as it used to) directly, and these BCC instructions
are emitted to the output or jitted directly if branches don't need
expansion. Only if branches need expansion are instructions rewritten
and created. This should make branch select faster, and eliminates the
Bxx instructions from the .td file.

convert PPC::BCC to use the 'pred' operand instead of separate predicate

Encode pc-relative conditional branch offset as pc+(num of bytes / 4). The
...
asm printer will print it as offset*4. e.g. bne cr0, $+8.
The PPC code emitter was expecting the offset to be number of instructions, not
number of bytes. This fixes a whole bunch of JIT failures.
