c503362914 - various tweaks to the immutable object support; also taught cp0
to simplify ($fxu< (most-positive-fixnum) e) => (fx< e 0) so we
  don't have any incentive in special casing length checks where
  the maximum length happens to be (most-positive-fixnum).

9a16156574 eliminated some direct assumptions that a vector's type/length field
is a fixnum and added meta-asserts to verify that it is in a couple of
others, to facilitate future changes to vector typing.  vectors are
now treated essentially like fxvectors, strings, and bytevectors.

6765641be0 - The scheme.h definition of Sfixnum(x) now uses multiply rather than
left shift to avoid counting on the behavior of << on negative numbers,
  which is undefined in C.
    mkheader.ss
- Fixed a couple of casts, one harmless and the other causing
  Sinteger64_value to return 0 for the most-negative I64 on 32-bit
  builds.
    number.c
- The configure-generated Makefile distclean target no longer removes
  zlib and nanopass, since they are logically part of the git clone.
  It does run make distclean in zlib.
