On HPPA, implement pg_memory_barrier() as pg_compiler_barrier(), which should be correct since this arch doesn't do memory access reordering, and is anyway better than the completely-nonfunctional-on-this-arch dummy_spinlock code. (But note this patch only fixes things for gcc, not for builds with HP's compiler.) Also, fix incorrect default definition of pg_memory_barrier as a macro requiring an argument. Also, fix incorrect spelling of "#elif" as "#else if" in icc code path (spotted by pgindent). This doesn't come close to fixing all of the functional and stylistic deficiencies in barrier.h, but at least it un-breaks my personal build. Now that we're actually using barriers in the code, this file is going to need some serious attention.
