Add support for a few simple fixups to the ARM Darwin asm backend. This allows
...
constant pool references and global variable refernces to resolve properly
for object file generation. For example,
int x;
void foo(unsigned a, unsigned *p) {
p[a] = x;
}
can now be successfully compiled directly to an (ARM mode) object file.
