one important workaround: PPCISD::CALL is matched by both PPCcall_ELF

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.

that touches BCC and requires us to write custom matching logic for
PPCcondbranch :(

This is a general clean up of the PowerPC ABI.  Address several problems and
bugs including making sure that the TOS links back to the previous frame,
that the maximum call frame size is not included twice when using frame
pointers, no longer growing the frame on calls, double storing of SP and
a cleaner/faster dynamic alloca.

Tell the codegen emitter that specific operands are not to be encoded, fixing
JIT regressions w.r.t. pre-inc loads and stores (e.g. lwzu, which we generate
even when general preinc loads are not enabled).

getting close.

clobber.  This allows LR8 to be save/restored correctly as a 64-bit quantity,
instead of handling it as a 32-bit quantity.  This unbreaks ppc64 codegen when
the code is actually located above the 4G boundary.

that takes a register and condition code.  Print these pieces of BLR the
right way, even though it is currently set to 'always'.

Next up: get the JIT encoding right, then enhance branch folding to produce
predicated blr for simple examples.
