* minor incompatible change: IMAGPART of a negative float returns 0.0, not
-0.0, consistent with a treatment of reals as complexes with an imaginary

* incompatible change: the compiler's internal representation of "source

SB-INTROSPECT functions, will misreport the location of signalled
conditions and/or definitions in top-level forms including backquotes and
commas.
* minor incompatible change: undefined syntaxes following
*READ-BASE*-related reader macros (such as #B, #O, #X, #R) now signal
reader errors.

* minor incompatible change: building with the SB-DEVEL feature inhibits
identical code folding at the end of the build of the SBCL system itself.
* enhancement: improve the compiler's knowledge of the dimensions of the
result of MAKE-ARRAY. (lp#2130477, thanks to Vasily Postnicov)
* enhancement: the SB-COVER contributed module has been made substantially
more robust; collecting coverage no longer inhibits various CLOS
optimizations. (For SBCL developers, it is now capable of reporting on
the coverage of the SBCL system itself, provided it is built with the new
:SB-COVER-FOR-INTERNALS build-time feature.)
* bug fix: REQUIREing the SB-MD5 contributed module no longer installs a
compiler optimization policy restriction of SPACE being at least 1.
* bug fix: don't miscompute the sizes of garbage collector data structures
for running with dynamic space heap sizes above 128GiB.
* bug fix: ENOUGH-NAMESTRING when the pathname and defaults arguments are
both logical pathnames with the same host returns a shorter string than
previously.

- Update to version 2.5.6
* enhancement: the compiler now recognizes when local functions (both named
and anonymous) are used only as downward funargs in many situations and
can stack allocate such closures even without explicit dynamic extent
declarations. See the updated manual entry on stack allocation for more
information and how user-code can declare funargs as downward.
* minor incompatible change: optimization notes for a variable declared to
be of type LIST will not be emitted for various transforms which are
defined to operate on (OR NULL VECTOR).
* minor incompatible change: some forms, including a THE form with an
invalid type specifier, or a CASE form with bad entries, no longer produce
a runtime error. (They continue to provide a full warning at
compile-time).
* platform support
** on arm64, breakpoint-based stepping is now thread-safe.
** on arm64, backtraces after interrupts should be more correct.
** on x86-64 with the immobile-space feature, calling from assembly

handler to customize behaviour on arena exhaustion.
* bug fix: address several bugs related to dynamic-extent declarations,
inference, and stack allocation.
* bug fix: the stack return page protection is temporarily disabled during
GC, so that GC can complete even if it needs to write in the return page.

* bug fix: the compiler's constraint derivation would sometimes not terminate.

restored to match the documentation. (lp#2096995, reported by Zach Beane)
