780413d462 Don't performance load/op/store transformation if op produces a floating point
or vector result. X86 does not have load/mod/store variants of those
instructions.

e50794adda - Enable x86 isel preprocessing by default unless -fast is specified.
- Also disable isel load folding if -fast.

06abd22b1a Make ppc64 jit kinda work right. About 2/3 of Olden passes with this,
there are clearly some encoding bugs lurking in there somewhere.

16c7fe5ca3 Fix target matching weights, so that ppc-darwin modules are codegen with the

b9ca92661c 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.
