for extra compiler options which need to be passed down in
compiler_flags.

(_cpp_lookup): If there is no entry for this string, create
one, of type T_VOID.
(_cpp_lookup_slot): Delete.

not hp == NULL.

do_unassert, cpp_defined): Use _cpp_lookup. Don't create a
node here, just fill in the value field properly. "Delete"
entries by setting the value field to T_VOID. Check for
hp->type == T_VOID, not hp == NULL.

adjusted by less than 256 bytes, use ret regardless of having any
callee-saved register to restore.
From-SVN: r33573

referenced bewteen the condition and the jump. Don't delete
anything but the jump.

STMT_EXPRs.
* optimize.c (struct inline_data): Add target_exprs field.

use the variable declared in the TARGET_EXPR as the remapped
DECL_RESULT.
(expand_call_inline): Update the pending target_exprs stack.
(optimize_function): Initialize the stack.

Update REORDER_BLOCK_EFF_HEAD and REORDER_BLOCK_EFF_END for new
block.
