[PATCH 0/5] [GOLD] PowerPC pc-relative support

This patch series adds support to gold for the new PowerPC prefix
instructions with pc-relative addressing.  (See git dd7efa7915 and
following for binutils and ld.bfd patches.)  As with the bfd linker,
I've added support for notoc calls even when pc-relative insns are not
available, but this won't often be needed as notoc calls really only
make sense when generating pc-relative code.

PATCH 2/5 makes changes to gold's target-independent .eh_frame
support, but powerpc is the only user of that code.

The patch series has been compiled with current gcc and older gcc that
defaults to -std=c++98.  Testing so far is fairly light.  I'll be
running more rigorous simulator tests before committing.
