0.8.7.6:
	Fix implementation of *-MOD32 and %LEA, as pointed out by Paul
	Dietz (on #lisp IRC) and APD (sbcl-devel 2004-01-04)
	... make %LEA a somewhat more generic operation; its BASE and
		INDEX arguments can now be any integers, not just 32-bit
		ones; SCALE and DISP are restricted to {1,2,4,8} and
		(SIGNED-BYTE 32) respectively.
	... write a modular-fun-optimizer for %LEA, cutting the integer
		arguments to the appropriate width; define a VOP for
		%LEA-MOD32.
	... add one of PFD's test cases to our test suite.
