SWDEV-3 - [msan] Fix __msan_maybe_ for non-standard type sizes.

	Fix incorrect calculation of the type size for __msan_maybe_warning_N
	call that resulted in an invalid (narrowing) zext instruction and
	\"Assertion `castIsValid(op, S, Ty) && \"Invalid cast!\"' failed.\"

	Only happens in very large functions (with more than 3500 MSan
	checks) operating on integer types that are not power-of-two.
