The code to create structure types did two things wrong:

1) It did not do bounds checking on the arrays used to hold the types of
structure members.

2) The static arrays for structure member types was 200.  LLVM can handle
structures with 256 (0-255) members.

I changed the size of the arrays and put in an assertion that should prevent
llvm-gcc from creating structures that the LLVM assembler can't handle.
