Daniel Sanders 52b4ce727a Recommit: [globalisel] Change LLT constructor string into an LLT-based object that knows how to generate it. 
Summary:
This will allow future patches to inspect the details of the LLT. The implementation is now split between
the Support and CodeGen libraries to allow TableGen to use this class without introducing layering concerns.

Thanks to Ahmed Bougacha for finding a reasonable way to avoid the layering issue and providing the version of this patch without that problem.

The problem with the previous commit appears to have been that TableGen was including CodeGen/LowLevelType.h instead of Support/LowLevelTypeImpl.h.

Daniel Sanders 8ebec37d26 Revert r297177: Change LLT constructor string into an LLT-based object ... 
More module problems. This time it only showed up in the stage 2 compile of
clang-x86_64-linux-selfhost-modules-2 but not the stage 1 compile.

Somehow, this change causes the build to need Attributes.gen before it's been
generated.

Daniel Sanders 983c9b98e9 Revert r296474 - [globalisel] Change LLT constructor string into an LLT subclass that knows how to generate it. 
There's a circular dependency that's only revealed when LLVM_ENABLE_MODULES=1.

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.
