diff: bugfix for agc tests.

[Tyson Dowd]

Hi,

Here's a fix for the agc tests that failed last night.

===================================================================


Estimated hours taken: 1

Fixed a bug with accurate GC grades.

compiler/handle_options.m:
	Set the stack_layout option in the option post-processing,
	not in the grade handling.
	(Previousle it was setting it with the grade, not according
	to the --gc option).
