33281864c1 If a PHI node has a single implicit_def source, replace it with an implicit_def instead of a copy.

b5fdc923d3 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.

811153a551 If we reload a virtual register that's already been assigned, we want to mark 
that instruction as its "last use". This fixes PR1925.

34d6b6a319 Update this test. Due to dag combiner improvements, we now compile 
f7/f11 to:

_f7:
	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

314e1cb7ee For PR1553: 
Change the keywords for the zext and sext parameter attributes to be 
zeroext and signext so they don't conflict with the keywords for the
instructions of the same name. This gets around the ambiguity.
