1dc7869025 1. IMPLICIT_DEF can *re-define* any register. 
2. Coalescer can now create an interesting situation where a register def can
   reaches itself without being killed.

that instruction as its "last use". This fixes PR1925.

15c2351a93 Update this test. Due to dag combiner improvements, we now compile 
f7/f11 to:

	eor r0, r0, #2, 2 @ -2147483648
	bx lr
_f11:
	bic r0, r0, #2, 2 @ -2147483648
	bx lr

instead of:

_f7:
	fmsr s0, r0
	fnegs s0, s0
	fmrs r0, s0
	bx lr

_f11:
	fmsr s0, r0
	fabss s0, s0
	fmrs r0, s0
	bx lr

instructions of the same name. This gets around the ambiguity.
