Ok, let's S be unconditional CIE flag without any CFA expression and if
a real need for CFA expression ever arises, we can always add another flag,
right?
If so, I'll work on finishing the libjava bits and start testing (so far
I only tested the cleanup-12 testcase on x86_64).
Also, do you think we should add .cfi_signal_frame assembler directive?
Currently to my knowledge only Alpha uses .cfi_* directives to describe
signal frame unwinding, so if we don't add it, alpha would need that stuff
rewritten into plain old explicit .eh_frame.
