In r279546 I disabled all frame pointer elimination at the front-end on
ARM-Darwin (and warned about it) because before that the backend had been
silently ignoring these options. It turns out we didn't ignore
-momit-leaf-frame-pointer though, just the more general -fomit-frame-pointer.
So this re-enables passing that down to CodeGen so that everything really does
continue working as before (with better diagnostics).

iOS (and other 32-bit ARM variants) always require a valid frame pointer to
improve backtraces. Previously the -fomit-frame-pointer and
-momit-leaf-frame-pointer options were being silently discarded via hacks in
the backend. It's better if Clang configures itself to emit the correct IR and
warns about (ignored) attempts to override this.

On Linux we pass in -fomit-frame-pointer flags (and similar)
automatically if optimization is enabled. Let's do the same thing on
CloudABI. Without this, Clang seems to run out of registers quite
quickly while trying to build code with inline assembly.

We're not that much into metals.
