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.

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.
