6f20ed8a6b ppc64 section group handling 
Two organizational changes to the array of additional info kept for
sections.
1) Move group info into a per-group allocated struct, in preparation
for future changes that need per-group accounting.
2) Expand the array to include output sections, which simplifies
sizing and removes the need for a separate output section array.

f6fe1ccd62 Don't change compressed input debug section names

5446cbdf82 ppc476 icache bug workaround 
This implements a work-around for an icache bug on 476 that can cause
execution of stale instructions when control falls through from one
page to the next.  The idea is to prevent such fall-through by
replacing the last instruction on a page with a branch to a patch
area containing the instruction, then branch to the next page.

The patch also fixes a number of bugs in the existing support for long
branch trampolines.
