several ways. We now warn for more of the return types, and correctly
locate the ignored ones. Also adds fix-it hints to remove the ignored
qualifiers. Fixes much of PR9058, although not all of it.

Patch by Hans Wennborg, a couple of minor style tweaks from me.

Teach CFGBuilder about null pointer constants in conditionals, and how they can be used to prune branches.  Fixes false null pointer dereference warning in PR 8183.

The previous codegen for the slow path (when values are in VFP / NEON
registers) was incorrect if the source is NaN.

The new codegen uses NEON vbsl instruction to copy the sign bit. e.g.
        vmov.i32        d1, #0x80000000
        vbsl    d1, d2, d0
If NEON is not available, it uses integer instructions to copy the sign bit.

Add test case (from PR 8876) for suppressing 'indirection of non-volatile null pointer...' warning due to reachability analysis.

Rd == 13.  Add opcode entries for the generic "sub (sp minus immediate)" operations.

Add test case for PR 9284, a false positive for -Warray-bounds that is now addressed using basic reachability analysis.

llvm-svn: 126291

Enhance Sema::DiagRuntimeBehavior() to delay some diagnostics to see if the related code is reachable.  This suppresses some
diagnostics that occur in unreachable code (e.g., -Warray-bound).

We only pay the cost of doing the reachability analysis when we issue one of these diagnostics.

llvm-svn: 126290

Migrate CFGReachabilityAnalysis out of the IdempotentOperationsChecker and into its own analysis file.

llvm-svn: 126288

Issue AnalysisBasedWarnings as part of calling Sema::PopBlockOrFunctionScope().  No real functionality change.

llvm-svn: 126287

Update Sema::DiagRuntimeBehavior() to take an optional Stmt* to indicate the code the diagnostic is associated with.

This Stmt* is unused, but we will use it shortly for pruning diagnostics associated
with unreachable code.

llvm-svn: 126286

Change -Warray-bounds logic to use DiagRuntimeBehavior in preparation for using basic dataflow to suppress warnings on unreachable array bounds checks.
