This patch to the Go frontend changes set_placeholder_struct_type to
use build_variant_type_copy rather than build_distinct_type_copy.
This is for PR 86343, which noted that the DECL_CONTEXT of the fields
in the copy were pointing to the wrong type. Using
build_variant_type_copy puts the types in right relationship for the
DECL_CONTEXT setting. Bootstrapped and ran Go testsuite on
x86_64-pc-linux-gnu. Committed to mainline.
