[PATCH 00/12] Reduce conditional compilation

[tbsaunde+gcc at tbsaunde dot org]

From: Trevor Saunders <tbsaunde+gcc@tbsaunde.org>

Hi,

This is a first round of patches to reduce the amount of code with in #if /
#ifdef.  This makes it incrementally easier to not break configs other than the
one being built, and moves things slightly closer to using target hooks for
everything.

each commit bootstrapped and regtested on x86_64-linux-gnu without regression,
and whole patch set run through config-list.mk without issue, ok?

Trevor Saunders (12):
  add default definition of EH_RETURN_DATA_REGNO
  remove some ifdef HAVE_cc0
  more HAVE_cc0
  always define HAVE_cc0
  make some HAVE_cc0 code always compiled
  provide default for RETURN_ADDR_OFFSET
  provide default for MASK_RETURN_ADDR
  reduce conditional compilation for HARD_FRAME_POINTER_IS_FRAME_POINTER
  remove #if for PIC_OFFSET_TABLE_REGNUM
  remove more ifdefs for HAVE_cc0
  provide default for INSN_SETS_ARE_DELAYED
  add default for INSN_REFERENCES_ARE_DELAYED
