Hi!
This patch series fixes PR124044 and speeds up LDS->flat address space
conversions by using GCN memory aperture registers to get the base
of the LDS mapping in the flat address space.
Tested on x86_64-linux-gnu as an offload compiler (on a GFX90a device),
and as a standalone amdgcn-amdhsa compiler.
As a fairly small change in a minor target, OK for trunk?
