The Go 1.18 library introduces specific types in
runtime/internal/atomic. This patch to the Go frontend recognizes and
optimizes the methods on those types, as we do with the functions in
runtime/internal/atomic.
While we're here avoid getting confused by methods in any other
package that we
This patch to the Go frontend and libgo implements the abi.FuncPCABI0
and abi.FuncPCABIInternal functions. The Go 1.18 standard library
uses an internal/abi package with two functions that are implemented
in the compiler. This patch implements them in the gofrontend, to
support the upcoming
Reset -mpower8-fusion for power9 inlining power8 functions, PR 102059.

It just fixes the issue that if a function is specifically declared as a power8
function, you can't inline in functions

This replaces the _Dir constructor that takes ownership of an existing
DIR* resource with one that takes a _Dir_base rvalue instead. This means
a raw DIR* is never passed around, but is always owned by a _Dir_base
object.
