  [SystemZ] Use reserved keywords in vecintrin.h

System headers should avoid using the "vector" and "bool" keywords
since those might be redefined by user code.  For example, using
<stdbool.h> before <vecintrin.h> will currently lead to compiler
errors.

Fixed by using the reserved "__vector" and "__bool" keywords
instead.  NFC otherwise.

  -----------
  [SystemZ] Avoid __INTPTR_TYPE__ conversions in vecintrin.h

Some intrinsics in vecintrin.h are currently implemented by
performing address arithmetic in __INTPTR_TYPE__ and converting
the result to some pointer type.  While this works correctly,
it leads to suboptimal code generation since many optimizers
cannot trace the provenance of the resulting pointers.

Fixed by using "char *" pointer arithmetic instead.
