60742ecabb Ignore MachO symbol flags in the upper nibble of n_desc. 
They don't impact the MCJIT rtdyld, so just mask them off for now.

1077c1fa88 Reapply commit 143214 with a fix: m_ICmp doesn't match conditions 
with the given predicate, it matches any condition and returns the
predicate - d'oh!  Original commit message:
The expression icmp eq (select (icmp eq x, 0), 1, x), 0 folds to false.
Spotted by my super-optimizer in 186.crafty and 450.soplex.  We really
need a proper infrastructure for handling generalizations of this kind
of thing (which occur a lot), however this case is so simple that I decided
to go ahead and implement it directly.

8282fc9e3b Fix pr11266. 
On x86: (shl V, 1) -> add V,V

Hardware support for vector-shift is sparse and in many cases we scalarize the
result. Additionally, on sandybridge padd is faster than shl.
