2d2cec1e9e Add support to print 4-, 8-, and 16- byte constant literals in special 
sections. e.g. On Darwin that would be .literal4 and .literal8.

372994be25 Switch to a very conservative heuristic for determining when loop-unswitching 
will be profitable.  This is mainly to remove some cases where excessive
unswitching would result in long compile times and/or huge generated code.

Once someone comes up with a better heuristic that avoids these cases, this
should be switched out.

f299857496 Don't implement AliasSetTracker::remove in terms of deleteValue. deleteValue 
causes the pointer to be removed from the underlying alias analysis
implementation as well.  This impl of remove is also significantly faster than
the old one.  This fixes:
