Only convert allocas to scalars if it is profitable. The profitability metric I
chose is having a non-memcpy/memset use and being larger than any native integer

1. The ARM Darwin *r9 call instructions were pseudo-ized recently.
Modify the ARMDisassemblerCore.cpp file to accomodate the change.

imm32 = SignExtend(imm24:'00', 32); // A8.6.23 BL, BLX (immediate)

Add C++ global operator {new,new[],delete,delete[]}(unsigned {int,long}) to the

This is different from any attribute we have. For example, you can delete the
allocators when their result is unused, but you can't collapse two calls to the
same function, even if no global/memory state has changed in between. The
noalias return states that the result does not alias any other pointer, but
instcombine optimizes malloc() as though the result is non-null for the purpose
of eliminating unused pointers.

That's it, I am declaring this a failure of the C++03 STL.
There are too many compatibility problems with using mixed types in
std::upper_bound, and I don't want to spend 110 lines of boilerplate setting up
a call to a 10-line function. Binary search is not /that/ hard to implement
correctly.
I tried terminating the binary search with a linear search, but that actually
made the algorithm slower against my expectation. Most live intervals have less
than 4 segments. The early test against endIndex() does pay, and this version is
25% faster than plain std::upper_bound().
