fc21f8ff14 Canonicalize insert/extractelement from single-element vectors into 
bitcasts.

It would also be possible to canonicalize the other way; does anyone 
have a preference?

4dc31369eb Switch lli back to using allocate-gvs-with-code behavior. 
- Otherwise we get two regressions in llvm-test for applications which run out
   of space.

 - Once the JIT memory manager is improved, this can be switched back.

3a4a884c16 Replace intersectWith with maximalIntersectWith. The latter guarantees that 
all values belonging to the intersection will belong to the resulting range.
The former was inconsistent about that point (either way is fine, just pick
one.) This is part of PR4545.

ConstantExpr and Instruction. This involves duplicating some code
between GetElementPtrInst and GEPOperator, but it's not a lot.

ca178908c8 Add a new Operator class, for handling Instructions and ConstantExprs 
in a convenient manner, factoring out some common code from
InstructionCombining and ValueTracking. Move the contents of
BinaryOperators.h into Operator.h and use Operator to generalize them
to support ConstantExprs as well as Instructions.

e2cf37b88c Untangle a snarl that I discovered when updating the mangler, 
starting in getCurrentFunctionEHName.  Among other problems,
we would try to privative a "foo.eh" label, but end up emitting
the label as _Lfoo.eh instead of L_foo.eh on darwin.  This is really
bad, and the linker has always tolerated these labels existing.
For now, just emit them as _foo.eh.

This patch also fixes problems with ".eh" labels on unnamed
functions and eliminates two strangely defined TargetAsmInfo
hooks.
