Remove obsolete SAMESIGN macro

The SAMESIGN macro was historically used as a helper for manual
integer overflow checks.  However, since commit 4d6ad3125 introduced
overflow-aware integer operations, this manual sign-checking logic is
no longer necessary.

The macro remains defined in brin_minmax_multi.c and timestamp.c, but
is not used in either file.  This patch removes these definitions to
clean things up.
