ARM asm parser wasn't able to parse a "mov" instruction while in Thumb
...
mode (only the "mov.w" variant). Now, when parsing "mov" in thumb mode,
default to the Thumb 1 versions/encodings.

subregisters:
When a value is in a subregister, at least report the location as being

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.
