The debugger sometimes lookup dynamically in the runtime to find ivar info of any Objective-C classes. It would be very helpful to debugger if the compiler encodes runtime version number in DWARF.

Add support for two additional DWARF attributes to encode Objective-C runtime version number.

BasicValueFactory: getMinValue/getMaxValue can be applied to any location type as specified by Loc::IsLocType().

 - Renamed to getDeclAlignInBytes since most other query functions
   work in bits.

 - Fun to track down as isIntegerConstantExpr was getting it right,
   but Evaluate() was getting it wrong. Maybe we should assert they
   compute the same thing when they succeed?

(Note: Eventually, commits like this will be handled via a pre-commit hook that
 does this automagically, as well as expand tabs to spaces and look for 80-col
 violations.)

modified in a way that may effect the trip count calculation. Change
IndVars to use this method when it rewrites pointer or floating-point
induction variables instead of using a doInitialization method to
sneak these changes in before ScalarEvolution has a chance to see
the loop. This eliminates the need for LoopPass to depend on
ScalarEvolution.

from the testcase, but the or/and/shift stuff still isn't zapped.

Zhongxing Xu. The resultant code is less than 1/2 the size of the original.

Key highlights:

- All CouldBeXXX methods have been removed. Checking for feasibility is now just
  done in the AddXXX methods.

- RangeSets now represent "all possible values" explicitly as the range set {
  [min, max] } instead of the empty set. The empty set now represents "no
  feasible values". This change consolidated much of the core algorithm to only
  have one code path instead of alternate paths that considered the empty set to
  represent "all possible falues."

IRgen no longer relies on isConstantInitializer, instead we just try
to emit the constant. If that fails then in C we emit an error
unsupported (this occurs when Sema accepted something that it doesn't
know how to fold, and IRgen doesn't know how to emit) and in C++ we
emit a guarded initializer.

This ends up handling a few more cases, because IRgen was actually
able to emit some of the constants Sema accepts but can't Evaluate().
For example, PR3398.
