* testsuite/libffi.call/closure_stdcall.c,
testsuite/libffi.call/closure_thiscall.c: Remove fragile stack pointer
checks. These files included inline assembly to save the stack

pieces of inline assembly, such as by saving a temporary value on the
stack across the call; observed with gcc -Os, and verified as spurious
through careful inspection of disassembly.
