6f1417c7d0 Clarify that OverflowingBinaryOperator is not used for SDiv, even though 
SDiv is a binary operation that can overflow.

f1c0daa6a7 Removed the DumpSymbolsandMacros and LoadSymbolsandMacros MCStreamer API as 
the parsing of the .dump and .load should be done in the assembly parser and
not have any need for an MCStreamer API.  Changed the code for now so these
just produce an error saying these specific directives are not yet implemented
since they are likely no longer used and may never need to be implemented.

00b05492f1 Revert the addition of hasNoPointerOverflow to GEPOperator. 
Getelementptrs that are defined to wrap are virtually useless to
optimization, and getelementptrs that are undefined on any kind
of overflow are too restrictive -- it's difficult to ensure that
all intermediate addresses are within bounds. I'm going to take
a different approach.

Remove a few optimizations that depended on this flag.

1a10a060cb Add plumbing for the `linker_private' linkage type. This type is meant for 
"private" symbols which the assember shouldn't strip, but which the linker may
remove after evaluation. This is mostly useful for Objective-C metadata.

This is plumbing, so we don't have a use of it yet. More to come, etc.

ec10fcbd04 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.

e45061eefe Convert more code to use Operator instead of explicitly handling both 
ConstantExpr and Instruction. This involves duplicating some code
between GetElementPtrInst and GEPOperator, but it's not a lot.

25a722cc45 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.

ffe0c407be 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.
