Eli Friedman 1f576831c9 When evaluating variably modified types for function parameters, dig out the
type as written from the ParmVarDecl; it's unclear whether the standard
(C99 6.9.1p10) requires this, but we're following the precedent set by gcc,
and hopefully nobody will ever ask about this again.

John McCall 77527a8e65 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.

John McCall 23c29fea92 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.

Daniel Dunbar 8fbe78f6fc 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).

Eli Friedman 9444638e4e Re-add a slightly more general version of the check from r72578; it is
actually necessary in some obscure cases.

Eli Friedman f4084708cd 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.
