Scott Burson, cmucl-imp, 2005-01-26 says pre-gc-dyn-usage is sometimes
equal to *gc-trigger*, and that was causing GC not to happen in some
cases on x86.  He said changing > to >= in sub-gc fixes this problem.

Implmement Pierre Mai's idea of adding 2 macros for setting *FEATURES*
and *RUNTIME-FEATURES* and setting them appropriately as files are
loaded so that recompiling CMUCL produces a result with the same set
of features.  *RUNTIME-FEATURES* is a subset of *FEATURES* that is
written out to internals.h so the C code can be compiled

A simple bootstrap with boot17 is needed.

Fix a problem with the consing-free allocation counter.  If you
allocate more than most-positive-fixnum bytes between two GCs, do a
normal, possibly consing addition instead of the fast dfixnum

Also clean up the exports of the dfixnum package and define a new
operator to increment a dfixnum by any integer.

Tested: full ITA testsuite, tried the profiler, tried various
allocation patterns which failed before this fix.

Make (time ...) and the profiler do precise measuring of space
allocation.  It will also not overflow or bomb out when consing
amounts cross most-positive fixnum.

The new profiler also has an interface to plug in your own print
function (also dictates sorting or results).

This is written on gencgc/x86 but tests indicated the fallsbacks for
other platforms work.

The dfixnum package included here is sketchy.

On x86 FreeBSD and Linux, change the way foreign symbol addresses are resolved.
They now go through a table -- effectively a new space in the core file.
Function references are resolved lazily, data references are resolved on startup
and when a .so is loaded.  The end result is that cores can be dumped that
contain references to symbols in shared libraries.  Also, the dependence of the core on addresses in the Lisp runtime is broken.

The linkage table feature is controlled by :linkage-table and LINKAGE_TABLE in C
runtime.  Several foreign symbols are now Lisp static symbols, so a cross
compile is required whether or not the new stuff is used.  I've checked in
boot4-cross-foreign-linkage.lisp that builds the compiler for linkage table; do whatever you usually do for the non-linkage table case:)  Seriously, lets start
a discussion on standardizing "cross compilation," not to mention the general
build procedure.

Merge in changes to the x86 backend from the gencgc branch, allowing
common binaries to be run on both:

* The immediate-stack storage class has been removed, this is
unnecessary as the descriptor-stack SC can be used. It may have once
been part of some GC stragety to reduce the number of stack slots that
needed to be noted for a GC.

* The object allocation has been abstracted and cleaned up. This
should produce slightly faster smaller code with CGC, and can be
compiled to support inline allocation with GENCGC.  CGC compiled code
will run under GENCGC, and GENCGC binaries that don't use inline
allocation will run under CGC.

* A random hash is now placed in the unused symbol object slot (the
symbol-hash slot). This saves flushing the info cache at each GC, and
may have other uses for symbol based hash tables. Should help MP

* Common set of static symbols used by both CGC and GENCGC.

* Corrections to the stack-ref VOP; now returns lisp objects not
unsigned numbers. Required some patches to debug-int.

* Inline unsigned/signed byte 32 to bignum allocation enabled.

* Support for the x86 xadd instruction applied to instance slot and
symbol values - may be handy for some MP code.

* Bump up the FASL file version from 1 to 2.
