(output_init_element): Don't call default_conversion for a STRING_CST if type is directly suitable for it.

(output_init_element): Don't call default_conversion
for a STRING_CST if type is directly suitable for it.
(digest_init): Eliminate a lot of code that checks the variable
'element', since element is always 0 in these code paths.

(build_c_cast): For (void *) (FOO *) 0, return a nop_expr
so it doesn't count as a null pointer constant.
(convert_for_assignment, build_binary_op): Pedantically warn about
that case if looking for a null_pointer_constant.
(build_conditional_expr): Likewise.

(attribute "length"): New attribute; put on all insns that don't have default
length.
(branch patterns): If conditional branch won't reach, take conditional branch
around an unconditional branch.

(plus): Split (plus (COMPARISON FOO ...) ...) at FOO.

Fix all callers.
(emit_move_sequence): Delete 3rd arg SCRATCH_REG.  Fix all
callers.  If operand1 is an invalid PIC address, then legitimize
it before doing anything else.

(SECONDARY_INPUT_RELOAD_CLASS): Delete case for invalid
PIC addresses.
(CONSTANT_ADDRESS_P): Reject invalid PIC addresses.
(LEGITIMATE_PIC_OPERAND_P): New macro.
