Make pgsql compile on FreeBSD-alpha.

Context diff this time.

Remove -m486 compile args for FreeBSD-i386, compile -O2 on i386.

Compile with only -O on alpha for codegen safety.

Make the port use the TEST_AND_SET for alpha and i386 on FreeBSD.

Fix a lot of bogus string formats for outputting pointers (cast to int
and %u/%x replaced with no cast and %p), and 'Size'(size_t) are now
cast to 'unsigned long' and output with %lu/

Remove an unused variable.
