libgo patch committed: Fix int64 alignment on 32-bit SPARC

[Ian Lance Taylor]

This patch to libgo fixes the expected alignment of int64 types on
32-bit SPARC.  Without this most calls to select fail at runtime, as
the compiler and the library disagree about the expected size of the
hselect struct.  Bootstrapped and ran Go testsuite on
x86_pc-linux-gnu, bootstrapped and ran a few libgo tests on
sparc-sun-solaris.  Committed to mainline.
