Subject: [PATCH] [WIP][LLVM] Add `__builtin_readsteadycounter` intrinsic and
buiiltin
Summary:
This patch adds a new intrinsic and builtin function mirroring the
existing `__builtin_readcyclecounter`. The difference is that this
implementation targets a separate counter that some targets have which
returns a fixed frequency clock that can be used to determine elapsed
time, this is different compared to the cycle counter which often has
variable frequency. This is currently only valid for the NVPTX and
AMDGPU targets.
