This adds subtarget features for AES, literal, and compare and branch
instruction fusion for different Cortex CPUs.

TargetMachine::shouldAssumeDSOLocal currently implies dso_local for such definitions.
Adding explicit dso_local makes these tests align with the clang -fno-pic behavior
and allow the removal of the TargetMachine::shouldAssumeDSOLocal special case.
Split tiny_model.ll to tiny-model-{static,pic}.ll
This is a code size win in code that takes offseted addresses
frequently, such as C++ constructors that typically need to compute
an offseted address of a vtable. It reduces the size of Chromium for
Android's .text section by 46KB, or 56KB with ThinLTO (which exposes
more opportunities to use a direct access rather than a GOT access).
Because the addend range is limited in COFF and Mach-O, this is
enabled for ELF only.

This feature enables the fusion of the address generation and a
corresponding load or store together.
