cindex/test_cursor.py: no need to skip implicit decls in tests

clang was fixed some time ago to always skip "builtins and other cruft" so
tools no longer need hacks like this.

Passes nosetests.

VirtualFileSystem: Fix a few directory traversal bugs in VFSWriter

There are a couple of issues with writing VFS maps that are awkward to
fix within the current mutually recursive approach. Instead, replace
the algorithm with an iterative version that uses an explicit stack of
directories.

Includes tests for cases the old approach was tripping on.

Frontend: Propagate ASTReaderListener API in ChainedASTReaderListener

ASTReaderListener's documentation states that visitInputFile will be
called based on the return values of needsInputFileVisitation and
needsSystemInputFileVisitation, but ChainedASTReaderListener may call
these methods on a child listener based on the values returned by the
other child.

Even worse, the calls to visitInputFile may be short-circuited due to
the use of the boolean or, so the calls to visit may not occur at all
for the second listener.

This updates ChainedASTReaderListener::visitInputFile to propagate the
ASTReaderListener behaviour to both children.

clang-format: Correctly calculate line lenghts for nest blocks.

If simple (one-statement) blocks can be inlined, the length needs to be
calculated correctly.

Before (in JavaScript but this also affects lambdas, etc.):
  var x = {
    valueOf: function() { return 1; }
  };

After:
  var x = {valueOf: function() { return 1; }};

This patch adds a helper class (CGLoopInfo) for marking memory instructions with llvm.mem.parallel_loop_access metadata.
It also adds a simple initial version of codegen for pragma omp simd (it will change in the future to support all the clauses).

clang-format: Correctly identify multiplications in braces init lists.

Before:
  int i{a *b};

After:
  int i{a * b};

Also fix unrelated issue where braced init lists were counted as blocks
and prevented single-line functions.

clang-format: [JS] Understand line breaks in concatenated strings.

Before:
  var literal = 'hello ' + 'world';

After:
  var literal = 'hello ' +
                'world';

There is no reason to concatenated two string literals with a '+' unless
the line break is intended.

clang-format: Store pointers to seen formatting states.

As the memory ownership is handled by the SpecificBumpPtrAllocator
anyway, there is no need to duplicate states when inserting them into
the Seen-set. This leads to an improvement of ~10% on the benchmark
formatting file.

No functional changes intended.
