for each AST context it knows about in a single
object.  This makes it faster to look up the
appropriate ASTImpoter for a given ASTContext
pair and also makes it much easier to delete all
metadata for a given AST context.

In the future, this fix will allow the
ClangASTImporter to propagate completion
information between the metadata for different
AST contexts as its minions move AST objects
around.

The code for checking Neon builtin pointer argument types was assuming that
there would only be one pointer argument.  But, for vld2-4 builtins, the first
argument is a special sret pointer where the result will be stored.  So,
instead of scanning all the arguments to find a pointer, have TableGen figure
out the index of the pointer argument that needs checking.  That's better than
scanning all the arguments regardless.  <rdar://problem/10448804>

the right direction.

file in the source manager. This allows us to properly create and use
modules described by module map files without umbrella headers (or
with incompletely umbrella headers). More generally, we can actually
build a PCH file that makes use of  file -> buffer remappings, which
could be useful in libclang in the future.

Change the ArrayBoundCheckerV2 to be more aggressive in reporting buffer overflows
when the offset is tainted. Previously, we did not report bugs when the state was
underconstrained (not enough information about the bound to determine if there is
an overflow) to avoid false positives. However, if we know that the buffer
offset is tainted - comes in from the user space and can be anything, we should
report it as a bug.

+ The very first example of us catching a taint related bug.
This is the only example we can currently handle. More to come...

rather than individually on behalf of each
ASTContext.  This allows the ASTImporter to know
about all containers of types, which will let it
be smarter about forwarding information about
type origins.  That means that the following
sequence of steps will be possible (after a few
more changes):

- Import a type from a Module's ASTContext into
  an expression parser ASTContext, tracking its
  origin information -- this works now.

- Because the result of the expression uses that
  type, import it from the expression parser
  ASTContext into the Target's scratch AST
  context, forwarding the origin information --
  this needs to be added.

- For a later expression that uses the result,
  import the type from the Target's scratch AST
  context, still forwarding origin information
  -- this also needs to be added.

- Use the intact origin information to complete
  the type as needed -- this works now if the
  origin information is present.

To this end, I made the following changes:

- ASTImporter top-level copy functions now
  require both a source and a destination AST
  context parameter.

- The ASTImporter now knows how to purge
  records related to an ASTContext that is
  going away.

- The Target now owns and creates the ASTImporter
  whenever the main executable changes or (in the
  absence of a main executable) on demand.
