John McCall 2725aa13ea Do the right thing for zero-initializing VLAs that don't have a zero 
bit-pattern.  It's not clear that this is actually useful given current
language restrictions.

Douglas Gregor 959d5a0cbd Implement support for variable length arrays in C++. VLAs are limited 
in several important ways:

  - VLAs of non-POD types are not permitted.
  - VLAs cannot be used in conjunction with C++ templates.

These restrictions are intended to keep VLAs out of the parts of the
C++ type system where they cause the most trouble. Fixes PR5678 and
<rdar://problem/8013618>.
