From 1dc106121b62562ead6e7d612fa136dc4b35cd5d Mon Sep 17 00:00:00 2001
From: Kyle Huey <khuey@kylehuey.com>

Subject: [PATCH] Add discriminators to DILocations when multiple functions are
inlined into a single point.
LLVM does not expect to ever see multiple dbg_declares for the same variable at the same
location with different values. proc-macros make it possible for arbitrary code,
including multiple calls that get inlined, to happen at any given location in the source
code. Add discriminators when that happens so these locations are different to LLVM.
This may interfere with the AddDiscriminators pass in LLVM, which is added by the
unstable flag -Zdebug-info-for-profiling.
Fixes #131944
