Mark the multiply which occurs as part of performing pointer
...
arithmetic on a VLA as 'nsw', per discussion with djg, and
implement pointer arithmetic (other than array accesses) and
pointer subtraction for VLA types.

Change the IR-generation of VLAs so that we capture bounds,
...
not sizes; so that we use well-typed allocas; and so that we
properly recurse through the full set of variably-modified types.

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
...
- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

Make VLAs usable, and make basic usage work correctly. Also, add a
...
simple test that actually does VLA codegen.
Note that despite the fact that the alloca isn't in the entry block, it
should dominate all uses; this is guaranteed by the restrictions on goto
into VLA scope in C99.
