[dev.regabi] cmd/compile: introduce cmd/compile/internal/ir [generated]
If we want to break up package gc at all, we will need to move
the compiler IR it defines into a separate package that can be
imported by packages that gc itself imports. This CL does that.
It also removes the TINT8 etc aliases so that all code is clear
about which package things are coming from.
This CL is automatically generated by the script below.
See the comments in the script for details about the changes.
