Improve performance of float overflow checks in btree_gist
The current code could do unnecessary calls to isinf() (two for the
argument values all the time while one could be sufficient in some
cases). zero_is_valid was never used but the result value was still
checked on 0 in the first position of the check.
This is similar to 607f8ce. btree_gist has just copy-pasted the code
doing those checks from the backend float4/8 code, as of the macro
CHECKFLOATVAL(), to do the work.
