Arthur Eubanks	a11bf9a7fb	[AMDGPU][Inliner] Remove amdgpu-inline and add a new TTI inline hook ... Having a custom inliner doesn't really fit in with the new PM's pipeline. It's also extra technical debt. amdgpu-inline only does a couple of custom things compared to the normal inliner: 1) It disables inlining if the number of BBs in a function would exceed some limit 2) It increases the threshold if there are pointers to private arrays(?) These can all be handled as TTI inliner hooks. There already exists a hook for backends to multiply the inlining threshold. This way we can remove the custom amdgpu-inline pass. This caused inline-hint.ll to fail, and after some investigation, it looks like getInliningThresholdMultiplier() was previously getting applied twice in amdgpu-inline (https://reviews.llvm.org/D62707 fixed it not applying at all, so some later inliner change must have fixed something), so I had to change the threshold in the test.

Valery Pykhtin	ffeb01c113	[AMDGPU] Don't constrain callees with inlinehint from inlining on MaxBB check ... Summary: Function bodies marked inline in an opencl source are eliminated but MaxBB check may prevent inlining them leaving undefined references.
