As I noted a long time ago in the comment on fixed_reg_p, the real
problem with saving fixed/global regs is that exception frame
unwinding might restore them.  So don't emit eh_frame info for any
such reg, and the unwinder won't restore them.

Also, tidy rs6000_savres_strategy.  Delaying some checks means we
won't iterate over regs quite so often.

	* config/rs6000/rs6000.c (rs6000_savres_strategy): Force inline
	restoring when fixed_reg_p, but allow out-of-line or stmw save.
	Check for user regs later to avoid unnecessary looping over regs.

This function is used to validate REG_EQUIV notes generated by ira,
and to validate potential insn combines performed by ira.  The two
conditions are not exactly the same, with reload being more
restrictive.  Separate them so more combines/moves can occur.

For example, this sequence from cfgexpand.c:expand_gimple_cond

This patch actually improves generated code, because REG_DEAD notes
used by the old insn scan are not always present.  On x86_64, see
gcc/wide-int-print.o:print_hex for an example of a function that is
smaller and uses one less callee saved reg.

	use DF infrastucture to find use and def insns.

From-SVN: r235660

Notes added by add_store_equivs are not used directly or indirectly by
combine_and_move_insns.  add_store_equivs can therefore run later
without affecting the output of combine_and_move_insns, and thus
add_store_equivs need not take into account potentially moved insns.
Since not all potentially combined/moved insns are in fact combined or
moved, this may allow add_store_equivs to add more REG_EQUIV notes.

grow_reg_equivs isn't needed until the reload reg_equivs array is
changed.

	ira.c (combine_and_move_insns): Move invariant conditions..
	(ira.c): ..to here.  Call combine_and_move_insns before
