For PR1194:
The bcreader counts on "primitive" types being inserted before they are
referenced in other types. With recent changes to the bcwriter, this fact
became exposed since IntegerType is no longer "primitive". We can no longer
count on all IntegerTypes being inserted early. This patch modifies
getOrCreateTypeSlot to insert any sub-type that can't possibly recurse
before we create the slot for the type. This has the benefit of reducing
the number of OpaqueType objects the reader needs to deal with.

Make the ModuleLevel datastructure more sane.  When a function-local value

These vectors are frequently large. Use std::vector instead.

Fix clients like this:

  delete ParseBytecodeFile(InputFilename, 0, &ErrorMessage);
  llvm_shutdown();
  delete ParseBytecodeFile(InputFilename, 0, &ErrorMessage);

The primitive type objects failed to ressurect themselves after shutdown, leading
to crashes in clients that used them after llvm_shutdown().

This solution isn't wonderful, because we clearly have static ctors.  However,
the code it replaces was just as bad, so it's not a regression.

Use int32_t and uint32_t to hopefully help weak compilers (cygwin) not
generate errors about being unable to resolve overloaded type.
