* libgcc2.c (__eh_ffetmnpc): Add support for machines that cannot
access globals after throw's epilogue when -fno-sjlj-exceptions is
used.
* rs6000.c (DONT_ACCESS_GBLS_AFTER_EPILOGUE): Likewise.
* mips.h (DONT_ACCESS_GBLS_AFTER_EPILOGUE): Likewise.
(INITIAL_ELIMINATION_OFFSET): Fix RETURN_ADDRESS_POINTER_REGNUM
for 64 bit words, with 32 bit pointers and variable endianness.
Fixes throwing across shared library lines (useful at times on mips and rs6000)
