Implement the PPC inline asm "L" modifier. This allows us to compile:

long long test(long long X) {

}
to:
foo r2 r3 r2 r3

dynamic-no-pic, and default.
PPC and x86 default is dynamic-no-pic for Darwin, pic for others.

If we have zero initialized data with external linkage, use .zerofill to
...
emit it (instead of .space), saving a bit of space in the .o file.
For example:
int foo[100];
int bar[100] = {};
when compiled with C++ or -fno-common results in shrinkage from 1160 to 360
bytes of space. The X86 backend can also do this on darwin.

Fix a couple of the FIXMEs, thanks to suggestion from Chris. This allows
...
us to load and store vectors directly at a pointer (offset of zero) by
using r0 as the base register. This also requires some asm printer work
to satisfy the darwin assembler.
For
void %foo(<4 x float> * %a) {
entry:
%tmp1 = load <4 x float> * %a;
%tmp2 = add <4 x float> %tmp1, %tmp1
store <4 x float> %tmp2, <4 x float> *%a
ret void
}
We now produce:
_foo:
lvx v0, 0, r3
vaddfp v0, v0, v0
stvx v0, 0, r3
blr
Instead of:
_foo:
li r2, 0
lvx v0, r2, r3
vaddfp v0, v0, v0
stvx v0, r2, r3
blr
