made Clang save and restore EBP around inline asm that only
clobbers it. This can make the existing EBP crash probe pass even
when the compiler still cannot allocate the 7-register i386 inline
asm used behind HAVE_7REGS.
Keep ebp_available for HAVE_6REGS and add a separate
x86_32_7regs probe for HAVE_7REGS.
