[m-rev.] diff: fix test case failure in tests/general/accumulator

[Simon Taylor]

Estimated hours taken: 0.1

tests/general/accumulator/Mmakefile:
	There appears to be a bug in value numbering which causes
	split.m to generate incorrect output, so turn it off for
	that test case.

	Deforestation optimizes away many of the opportunities for
	accumulator introduction in the test cases, so turn it off.
