smaller than the preferred alignment, but so that the target can actually
specify a minimum alignment if needed.  This fixes some objc protocol
failures Devang tracked down.

When a function has FP, the register scavenging spill slot offset already
was calculated.

For VFP2 fldm, fstm instructions, the condition code is printed after the address mode and size specifier. e.g. fstmiaseq, not fstmeqias.

set this way is _SLOW_.  Somewhere down the line, I'll look at speeding it up.

If there is an empty block between a source and its successor block, it still requires a unconditional branch.

Very first part of a GVN-PRE implementation.  It currently performs a bunch of analysis, and nothing more.  It is also quite slow for the moment.  However,
it should give a sense of what's going on.
