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

(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.

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.
