Tim Northover 862758ec14 GlobalISel: pass Function to lowerFormalArguments directly (NFC). 
The only implementation that exists immediately looks it up anyway, and the
information is needed to handle various parameter attributes (stored on the
function itself).

Tim Northover 406024a108 GlobalISel: implement simple function calls on AArch64. 
We're still limited in the arguments we support, but this at least handles the
basic cases.

Tom Stellard 000c5af3e6 AMDGPU: Add skeleton GlobalIsel implementation 
Summary:
This adds the necessary target code to be able to run the ir translator.
Lowering function arguments and returns is a nop and there is no support
for RegBankSelect.
