MachineRelocations, "stub" always refers to a far-call stub or a
load-a-faraway-global stub, so this patch adds "Far" to the term. (Other stubs
are used for lazy compilation and dlsym address replacement.) The variable was
also inconsistent between the positive and negative sense, and the positive
sense ("NeedStub") was more demanding than is accurate (since a nearby-enough
function can be called directly even if the platform often requires a stub).
Since the negative sense causes double-negatives, I switched to
"MayNeedFarStub" globally.

When instantiating a field decl, make sure to clone its attributes. With this change FileCheck no longer crashes when it's run without any arguments.

When looking up and adding substitutions to the substitution table, make sure to always use the canonical declaration. With tihs change, FileCheck compiles and links but crashes during startup.

Remove Checker::CheckType() (and instead using CheckerVisitor::PreVisitDeclStmt()), and refactor VLASizeChecker to have only one Checker subclass (not two) and to not use the node builders directly (and instead use the newer CheckerContext).

  used by machine LICM and other MI passes to perform CSE.
- Teach Thumb2InstrInfo::isIdentical() to check two t2LDRpci_pic are identical.
  Since pc relative constantpool entries are always different, this requires it
  it check if the values can actually the same.
