Merge remote-tracking branch 'origin/master' into stage2-whole-file-astgen

Conflicts:
 * src/codegen/spirv.zig
 * src/link/SpirV.zig

the source file name when a compile error occurs otherwise std lib
contributors are going to see some confusing CI failures when they cause
stage2 AstGen compile errors.
