ffd9c3dd4a If subprogram die is not available then construct new one. 
This can happen if debug info is processed lazily.

fd07cf56cd Adjust context for the global variables that are not at file scope, e.g. 
void foo() { static int bar = 42; }
Here, foo's DIE is parent of bar's DIE.

540b05d227 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.

85c005af0d Don't treat malloc calls with non-matching prototype as malloc. 
Fixes second part of PR5130, miscompilation in FreeBSD kernel, where malloc takes 3 params,
and *does* initialize memory.

cf0fe8d813 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.

7aa3c781b4 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.
