This patch to the Go frontend stops putting constants passed to the
predeclared print/println functions in temporaries.  This was an
accidental recent change when the printlock function was introduced.
The print/println functions are unusual in that integer constants are
treated as int64 or uint64 when necessary.  Putting them in
temporaries breaks that, forcing the constants to int, which means
that the wrong thing happens on 32-bit systems.  This fixes GCC PR
78145.  Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.
Committed to mainline.

Ian
