cmd/gc: make bitmaps shorter
Sort non-pointer-containing data to the low end of the
stack frame, and make the bitmaps only cover the
pointer-containing top end.
Generates significantly less garbage collection bitmap
for programs with large byte buffers on the stack.
Only 2% shorter for godoc, but 99.99998% shorter
in some test cases.
Fixes arm build.
