0743c42807 Merge remote-tracking branch 'upstream/master' into dataflow-indirect-args 
Accepted test results that were in semantic merge conflict between
these branches. The changed results are due to a bug that that's part of
https://github.com/github/codeql-c-analysis-team/issues/35.

c5ac357bfc C++/C#: Fix bad overlap sanity failures 
`Instruction.getDefinitionOverlap()` depends on `SSAConstruction::getMemoryOperandDefinition()`, which in turn depends on `SSAConstruction::hasMemoryOperandDefinition()`. When the definition in question came from a `Chi` instruction, `hasMemoryOperandDefinition()` incorrectly bound `overlap` to the overlap relationship between the original (non-`Chi`) instruction and the use. The fix is to make use of the `actualDefLocation` parameter to `getDefinitionOrChiInstruction()`, which specifies the location for the result of the `Chi` in that case.

f6f9afe462 C++: Implement Instruction.isResultConflated 
This predicate replaces `isChiForAllAliasedMemory`, which was always
intended to be temporary. A test is added to `IRSanity.qll` to verify
that the new predicate corresponds exactly with (a fixed version of) the
old one.

The implementation of the new predicate,
`Cached::hasConflatedMemoryResult` in `SSAConstruction.qll`, is faster
to compute than the old `isChiForAllAliasedMemory` because it uses
information that's readily available during SSA construction.

9922958bf1 C++: Fix failed tests 
Added a new `StaticLocalVariable` class, which made several other pieces of the original change a bit cleaner.

Fixed test failures due to a mistake in the original `CFG.qll` change.

Added a test case for static local variables with constructors.

Removed the `Uninitialized` instruction from the initialization of a static local, because all objects with static storage duration are zero-initialized at startup.

Fixed expectations for `SignAnalysis.ql` to reflect that a bad result is now fixed.

7a6ec83572 C++: No CopyValue for immediately discarded exprs 
Expressions like the `e` in `e;` or `e, e2`, whose result is immediately
discarded, should not get a synthetic `CopyValue`. This removes a lot of
redundancy from the IR.

To prevent these expressions from being confused with the expressions
from which they get their result, the predicate
`getInstructionConvertedResultExpression` now suppresses results for
expressions that don't produce their own result. This should fix the
mapping between expressions and IR data-flow nodes.
