Pass in frame pointer omitting compiler flags for CloudABI as well.
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.
