Turn on -O2 for the RTS by default
Optimisation now makes a difference when compiling .cmm code, because
it enables the optimisation passes in CmmPipeline. Recently validate
has not been optimising the .cmm code because it uses SRC_HC_OPTS=-O0,
which explains why I couldn't reproduce #7366 in validate (the bug
miscompiled rts/PrimOps.cmm).
