* config/tc-i386.c (i386_operand): Don't set the size of an
 	immediate address based solely on the suffix and the mode.

	* config/tc-i386.c (md_assemble): Add assertion to make sure
	overlap2 does not set Imm.

* config/tc-i386.c (md_assemble): Add assertion to make sure
overlap2 does not set Imm.
* config/tc-i386.c (space_chars): Remove. The scrubber converts
sequences of whitespace to a single space.
(is_space_chars): Just compare with space.
