Authentication-results: sourceware.org; auth=none

This patch by Chris Manghane fixes a bug in the escape analysis pass
of the Go frontend.  The slice created to hold the values passed to a
varargs parameter would always escape.  This also fixes a bug in which
a stack-allocated varargs parameter was incorrectly initialized in
some cases.  Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.
Committed to mainline.

Ian
