Because PPC lacks store-immediate, remove the instruction
that implies that it exists.  Replace it with storezero for
the special case of storing zero, because R0 is reserved zero
for Go (though the assembler knows this, do it in SSA).

Also added address folding for storezero.
(Now corrected to use right-sized stores in bulk-zero code.)

…laneous"

Added support for ClosureCall, DeferCall, InterCall
(GoCall not yet tested).

Added support for GetClosurePtr, IsNonNil, IsInBounds, IsSliceInBounds, NilCheck
(Convert and GetG not yet tested)

Still need to implement NilCheck optimizations.
Fixed move boolean constant, order of operands to subtract.

to GC.

Passes ssa_test.

Requires a few new instructions and some scratchpad
memory to move data between G and F registers.

Also fixed comparisons to be correct in case of NaN.
Added missing instructions for run.bash.
Removed some FP registers that are apparently "reserved"
(but that are also apparently also unused except for a
gratuitous multiplication by two when y = x+x would work
just as well).

Currently failing stack splits.

This time with the cherry-pick from the proper patch of
the old CL.

Stack size increased.
Corrected NaN-comparison glitches.
Marked g register as clobbered by calls.
Fixed shared libraries.

live_ssa.go still disabled because of differences.
Presumably turning on more optimization will fix
both the stack size and the live_ssa.go glitches.

Enhanced debugging output for shared libs test.

Rebased onto master.

Enabled checks (except for DUFF-ops which aren't implemented yet).
Added ppc64le to relevant test.

Also updated register list to reflect no-longer-reserved-
for-constants status (file was missed in that change).
