Fix the root cause of the bootstrap failure:
...
There was no way to check if a given register/mode pair was valid. We now return
an error code (-2) instead of asserting. If anyone thinks that an assert
at this point is really needed, we can autogen a hasValidDwarfRegNum instead.

According to PR2536, the old spiller had trouble with the IMPLICIT_DEF in this
code:
%reg1028<def> = MOV16rm %reg0, 1, %reg0, <ga:g_5>, Mem:LD(2,2) [g_5 + 0]
%reg1039<def> = IMPLICIT_DEF
%reg1038<def> = INSERT_SUBREG %reg1039, %reg1028, 2
%reg1025<def> = AND32ri %reg1038, 65534, %%EFLAGS<imp-def>
However, today we emit a zero-extending load instead:
%vreg10<def> = MOVZX32rm16 %noreg, 1, %noreg, <ga:@g_5>, %noreg; %mem:LD2[@g_5] GR32:%vreg10
%vreg0<def> = AND32ri %vreg10, 65534, %%EFLAGS<imp-def,dead>; %GR32:%vreg0,%vreg10
This makes the test pointless since it no longer creates the spiller hazard.

Fix the inliner to maintain the current de facto invoke semantics:
...
- the selector for the landing pad must provide all available information
about the handlers, filters, and cleanups within that landing pad
- calls to _Unwind_Resume must be converted to branches to the enclosing
lpad so as to avoid re-entering the unwinder when the lpad claimed it
was going to handle the exception in some way
This is quite specific to libUnwind-based unwinding. In an effort to not
interfere too badly with other unwinders, and with existing hacks in frontends,
this only triggers on _Unwind_Resume (not _Unwind_Resume_or_Rethrow) and does
nothing with selectors if it cannot find a selector call for either lpad.
