In particular fix fd_select.go to handle the case where a file
descriptor is closed by one goroutine while another goroutine
is waiting for it.

(rs6000_emit_prologue): Generate frame_ptr_rtx as we need it.
Set frame_reg_rtx to r11 whenever r11 is needed, and merge
frame offset adjustment for out-of-line save with copy from sp.
Simplify condition controlling whether cr is saved early or
late. Use ptr_regno_for_savres to verify correct reg is set
up for out-of-line saves. Pass the actual pointer reg used to
rs6000_emit_savres_rtx so rtl matches insns in out-of-line
function. Rearrange spe vars so code is similar to that
elsewhere in this function. Don't update frame_off when spe
save code will restore r11. Use emit_frame_save for spe and
gpr saves. Consolidate darwin out-of-line gpr setup with that
for other abis. Don't assume frame_offset is zero and frame
reg is sp when setting up altivec reg saves, and calculate
exact offset requirement.
(rs6000_emit_epilogue): Use HOST_WIDE_INT for frame_off. Tidy
spe restore code. Consolidate darwin out-of-line gpr setup
with that for other abis.
