[Bug c/27301] [4.0/4.1/4.2 Regression] ICE on convoluted inline asm with "m" (statement expression and vla)

Hmm, interesting, we have a TARGET_EXPR before gimplifying:
  __asm__ __volatile__(""::"m" TARGET_EXPR <D.1284, {
    typedef struct
    {
      char x[0:(unsigned int) ((int) SAVE_EXPR <n> - 1)];
    } struct struct
    {
      char x[0:(unsigned int) ((int) SAVE_EXPR <n> - 1)];
    };
    struct
    {
      char x[0:(unsigned int) ((int) SAVE_EXPR <n> - 1)];
    } * p = (struct
    {
      char x[0:(unsigned int) ((int) SAVE_EXPR <n> - 1)];
    } *) ptr;


Which might be the real issue.
The C++ front-end rejects this code as a VLA type is invalid even for GNU C++.
