eliminate use of _Unwind_GetRegionStart on ARM, take 2
The previous patch to eliminate _Unwind_GetRegionStart on ARM suffered from
major misalignment exceptions. The function pointers in the @LPStart fields
weren't resolved by the linker but apparently required runtime fixup by glibc.
Since they are always misaligned (the LSDA blob starts aligned with a format
byte followed by the @LPStart pointer), each @LPStart value resulted in two
alignment exceptions. Ouch.
The new version of the patch makes the @LPStart pointers PC-relative which
eliminates the runtime fixups and thus the alignment exceptions.
