a803c712dd Instead of printing unnecessary basic block labels as labels in 
verbose-asm mode, print comments instead. This eliminates a non-comment
difference between verbose-asm mode and non-verbose-asm mode.

Also, factor out the relevant code out of all the targets and into
target-independent code.

e87add4b88 remove predicate simplifier, it never got the last bugs beaten 
out of it, and jump threading, condprop and gvn are now getting
most of the benefit.  This was approved by Nicholas and Nicolas.

where the element is of a basic builtin type.  For example, to get
an i8* use getInt8PtrTy.

d6da133b85 In Thumb1, the register scavenger is not always able to use an emergency 
spill slot. When frame references are via the frame pointer, they will be
negative, but Thumb1 load/store instructions only allow positive immediate
offsets. Instead, Thumb1 will spill to R12.

a3cf123e86 strength reduce a ton of type equality tests to check the typeid (Through 
the new predicates I added) instead of going through a context and doing a
pointer comparison.  Besides being cheaper, this allows a smart compiler
to turn the if sequence into a switch.

18cecec6a0 SSI needs to require DT and DF transitively, since it uses them outside of its runOnFunction. 
Similarly, it can be marked setPreservesAll, since it does no work in its runOnFunction.
