Subject: Go patch committed: use a cache for interface methods
Authentication-results: sourceware.org; auth=none

The Go frontend constructs the list of interface methods in a few
different cases.  These can be called frequently, but the list is
reconstructed each time.  This patch by Than McIntosh uses a cache.
It reduces the memory usage of the frontend from around 16mb to around
10mb when compiling the fmt package.  Bootstrapped and ran Go
testsuite on x86_64-pc-linux-gnu.  Committed to mainline.

Ian
