compiler: Report errors after evaluating invalid constant.
The fix for golang/go#11541 made the assertion that getting an invalid
Numeric_constant after evaluating an invalid constant must result in
an error in a binary expression. However, a Numeric_constant can be
invalid if it is unset, which occurs when either operand cannot be
converted to the right type. These errors are issued after the
Numeric_constant is lowered.

Remove undefined behaviour from builtins-20.c
builtins-20.c had:
if (cos((y*=2, -fabs(tan(x/-y)))) != cos((y*=2,tan(x/y))))
link_error ();
which is undefined behaviour. The test expected that y had the same
value in x/y and x/-y, but gimplification actually implements the
"obvious" interpretation, multiplying y by 2, using it for one cos call,
then multiplying it by 2 again and using it for the other cos call.
The file has other (valid) tests that side-effects don't block
optimisation, such as:
if (cosf((y*=3, -x)) != cosf((y*=3,x)))
link_error ();
so this patch simply removes this instance.
Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.
