7bfc442b2d Some autoconf tests use module level inline asm to test compiler's handling of
.cfi_startproc. e.g. libffi:

 $ cat confopt.c 
asm (".cfi_startproc\n\t.cfi_endproc");

int main () { return 0; }

Teach MC / dwarf emission to handle these cfi directives which essentially
create an empty frame.

b33129ebad Thumb1 ADD/SUB SP instructions are predicable in Thumb2 mode.
Add the predicate operand to the instructions. Update the back end
accordingly where the instructions are used. Restrict the SP operands
to actually only be SP, as otherwise these break assembly parsing for the
normal instruction variants.

2cd76365f2 Add the sentinal "no handle" value to the ResumeInst.
A value of -1 at a call site tells the personality function that this call isn't
handled by the current function. Since the ResumeInsts are converted to calls to
_Unwind_SjLj_Resume, add a (volatile) store of -1 to its 'call site'.

79b1f95f89 Don't replace *all* uses with the new stuff.
This is not necessarily the first or dominating use of the EH values. The IR
breaks if it's not. So replace the specific value in the instruction with the
new value.

acd21d7162 Look at the end of the entry block for an invoke.
The invoke could be at the end of the entry block. If it's the only one, then we
won't process all of the landingpad instructions correctly. This code is
currently ugly, but should be made much nicer once the new EH switch is thrown.

b65ec7c64f Move ARM frame-unwinding EHABI handling a touch earlier.
It should go before AsmPrinter MC pseudo expansion since it's based on
MachineInstr, not MCInst. Otherwise any frame related pseudo instructions
may be missed.
