* 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
pointer before and after the call, and compare the values. However,
compilers can and do leave the stack in different states for these two
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.
