35c6dd2400 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.

428e17c613 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.

There's a circular dependency that's only revealed when LLVM_ENABLE_MODULES=1.

This reverts commit r293503.

Revert while I investigate some of the buildbot failures.

d79f714b0b 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).

3b3a95a083 GlobalISel: implement simple function calls on AArch64.
We're still limited in the arguments we support, but this at least handles the
basic cases.

65b55414cc 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.
