Summary:
Add partial support for the hasDeclaration() matcher in the dynamic layer.
This matcher has some special logic to allow any type that has a getDecl() method.  We do not support this right now.

Currently with clang:
$ clang -O20 foo.c
error: invalid value '20' in '-O20'

With the patch:
$ clang -O20 foo.c
warning: optimization level '-O20' is unsupported; using '-O3' instead.

This matches the gcc behavior (with a warning added)

FixedCompilationDatabase (FCD) requires that the arguments it consumes after
'--' must not include positional parameters or the argv[0] of the tool. This
patch relaxes those restrictions.

This adds -freroll-loops (and -fno-reroll-loops in the usual way) to enable
loop rerolling as part of the optimization pass manager. This transformation
can enable vectorization, reduce code size (or both).

Briefly, loop rerolling can transform a loop like this:

for (int i = 0; i < 3200; i += 5) {
  a[i]     += alpha * b[i];
  a[i + 1] += alpha * b[i + 1];
  a[i + 2] += alpha * b[i + 2];
  a[i + 3] += alpha * b[i + 3];
  a[i + 4] += alpha * b[i + 4];
}

into this:

for (int i = 0; i < 3200; ++i) {
  a[i] += alpha * b[i];
}

Loop rerolling is currently disabled by default at all optimization levels.

New rules of invalidation/escape of the source buffer of memcpy: the source buffer contents is invalidated and escape while the source buffer region itself is neither invalidated, nor escape.
In the current modeling of memcpy the information about allocation state of regions, accessible through the source buffer, is not copied to the destination buffer and we can not track the allocation state of those regions anymore. So we invalidate/escape the source buffer indirect regions in anticipation of their being invalidated for real later. This eliminates false-positive leaks reported by the unix.Malloc and alpha.cplusplus.NewDeleteLeaks checkers for the cases like

char *f() {
  void *x = malloc(47);
  char *a;
  memcpy(&a, &x, sizeof a);
  return a;
}

clang -cc1 skips the driver so it never made sense to include these with the
Driver tests.

Basic type tests and flag tests generally both go in Frontend.

Now that the final -cc1 tests have been moved out of test/Driver, add a
local substitution to enforce and detect future mistakes.

These miscategorized tests were probably the source of confusion in r194817.
