[PATCH, checked in] Reorg of header files

[Eric Christopher]

Colossal reorg patch. 

Changes: Moves to dwarf2. Removes ecoff.h (mips-ecoff still exists, but
didn't build before/after). -gstabs still works and is now just plain
stabs, -gcoff (and the -mmdebug for gas) only work under ecoff. Header
files removed. No regressions with the exception of mips32 which has a
sim problem around ldc1 (and since mipsisa32 is now hard float this
shows up).  gdb looks better in tests as well.

Couple of things:
1) wasn't sure where to document new configure options.
2) or to document that gofast is now turned off by default
