The Mach-O writer puts the unwinding records in a __unwind_info
section, so just find the appropriate section and use its contents
instead of forcing it to be at the end of the segment's memory space.
Create an overload of UnwindingRecordsPlatform::RegisterExecutableMemory
that takes a pointer to the start of the unwinding records for use by
the Mach-O loader.
Add __unwind_info for any executable segments that are not the text
segment as well.
Instead of testing host/target windows plus 64-bit arch, use the
defines provided by platform/unwinding_records.h in the Mach-O
writer and the ELF and Mach-O loaders.
