For 386 and amd64, the compiler will use information from PGO to align certain
hot blocks in loops.  This improves performance an additional 1-1.5% at
a cost of an additional 0.1% text and binary size.  This is currently only implemented
on 386 and amd64 because it has not shown an improvement on other platforms.
Hot block alignment can be disabled with `-gcflags=[<packages>=]-d=alignhot=0`
