(lang_identifier): Add limbo_value field for out of
scope block level extern declarations.
(IDENTIFIER_LIMBO_VALUE): New define, to access that field.

From-SVN: r2129

(pushdecl): Check an extern decl against both previous global and
previous limbo declarations.  For global declarations, clear limbo
value field.  For block level extern declarations, set limbo field
if zero.
(grokdeclarator): If this is a block level extern, then allocate
it on the permanent obstack, not the temporary obstack.

Replace `(unsigned)' with `(unsigned long)'.  When
evaluating << and >>, compute the correct answer without shifting
by more than HOST_BITS_PER_LONG, or by a negative quantity.
(integer_overflow, left_shift, right_shift): New functions.

Some code come from output_zdepi.
(output_zdepi): Removed. (depi_cint_operand): New name for zdepi_operand.
(consec_zeros_p, and_operand, ior_mask_p, ior_operand,
output_and, output_ior): New functions.
(output_load_address): Removed.  Nothing uses it.

(CONST_OK_FOR_LETTER_P): Add 'O' and 'P'.

(several patterns): Make sure # of attribute alternatives
match # of constraint alternatives.
Return assembler output template instead of calling output_asm_insn.
Don't write to operands[n] for n >= max operand number in the
pattern, use xoperands instead.
(casesi): Rewrite.  Used to be buggy and slow.
(and-not patterns): Make them canonical.  Put operands in the right order.
(negsi2): Don't use @ for just one output template.
(movstrsi): Change `!= 4' => `< 4' in test for alignment.
(adddi3): Extend to handle CONST_INT.
(ior-with-immediate optimizer): New pattern.
(and-with-immediate optimizer): New pattern.
(sCC, bCC expanders): Remove constraints.
(high:DI recognizer): Add return \"\".

	* pa.md	(non-[cf]branch define_delay): Use a single delay description
	for the delay slots in "branch", "call", and "milli" insns.
	(fbranch define_delay): fbranches have a single delay slot which
	may be nullified when the branch is taken (regardless of direction
	or distance to the target.)
	(in_branch_delay attribute): Disallow fbranch insns explicitly.
	(floating point branches): Use "fbranch" attribute for these insns.
	Update output template to properly handle nullification.
