parameter with a default value, instead of just hardcoding it in the
implementation. The limit of MaxLookup = 6 was introduced in r69151 to fix
a performance problem with O(n^2) behavior in instcombine, but the scalarrepl
pass is relying on getUnderlyingObject to go all the way back to an AllocaInst.
Making the limit part of the method signature makes it clear that by default
the result is limited and should help avoid similar problems in the future.
This fixes pr6126.

missing ones are libsupport, libsystem and libvmcore. libvmcore is
currently blocked on bugpoint, which uses EH. Once it stops using
EH, we can switch it off.
This #if 0's out 3 unit tests, because gtest requires RTTI information.
Suggestions welcome on how to fix this.

if one of the vectors didn't have elements (such as undef). Fixes PR 6096.
Fix an issue in the constant folder where fcmp (<2 x %ty>, <2 x %ty>) would
have <2 x i1> type if constant folding was successful and i1 type if it wasn't.
This exposed a related issue in the bitcode reader.

This patch also cleans up code that expects there to be a bitcast in the first argument and testcases that call llvm.dbg.declare.
It also strips old llvm.dbg.declare intrinsics that did not pass metadata as the first argument.

and use them to avoid a copy of a string in getNameWithPrefix in
the common case. It seems like Value::setName and other places
should use this as well?

that I want to completely eliminate. Add fixme's so I remember this
in the future, and add the missing helper that they should be upgraded
to use instead.

instead of returning it in an std::string. Based on this change:
1. Change TargetLoweringObjectFileCOFF::getCOFFSection to take a StringRef
2. Change a bunch of targets to call makeNameProper with a smallstring,
making several of them *much* more efficient.
3. Rewrite Mangler::makeNameProper to not build names and then prepend
prefixes, not use temporary std::strings, and to avoid other crimes.

- getToken is modeled after StringRef::split but it can split on multiple
separator chars and skips leading seperators.
- SplitString is a StringRef::split variant for more than 2 elements with the
same behaviour as getToken.

Make InsertDbgValueIntrinsic() and get Offset take and recieve a uint64_t.
Get constness correct for getVariable() and getValue().
