Tweak to be slightly more configurable regarding the host binary

Developers building with an existing SBCL as a host, which is not
installed as "sbcl" in the path, or which needs a --core option, can
now set XC_LISP and XC_CORE prior to invoking Previously,
such a host could only be used with after custom
modifications to the script.

The default behaviour is unchanged.

Add dyndebug flags backtrace_when_lost, sleep_when_lost

Available when :SB-QSHOW is enabled, these settings can be enabled
through the SBCL_DYNDEBUG environment variable to customize SBCL's
behaviour prior to entry to ldb.

With backtrace_when_lost, lossage shows a backtrace before
continuing with the lossage handler as usual. (Thanks to Dmitry
Kalyanov for this idea, here committed as a dyndebug option.)

With sleep_when_lost activated, the monitor is preempted, and SBCL
will instead cease to do anything except for a OS-level sleep call.
This behaviour has proven useful in preserving a failing thread's
current state until an external debugger can be attached.

Add odxprint, a replacement for FSHOW which can be configured at run-time

- A new macro odxprint(flag, "fmt", ...) performs the equivalent of
a printf("fmt", ...), but only if `flag' has been enabled at

- Environment variables can be used to set flags, using either
SBCL_DYNDEBUG="flag1 flag2 flag3" syntax, or
SBCL_DYNDEBUG__FLAG1="nonempty string" syntax.

- Lisp feature SB-QSHOW enables support for odxprint-based FSHOW.
(Users who prefer to edit runtime.h to enable QSHOW can still do
so...) SB-QSHOW is enabled by default on Windows, where the
odxprint mechanism was first used.

- Implement FSHOW, FSHOW_SIGNAL on top of odxprint. Corresponding
flags are called fshow, fshow_signal.

- For gencgc_verbose, support a flag of the same name, since it is
conditional on QSHOW (inspite of not being implemented on top of

- Does not yet support odxprint features specific to Windows debugger
integration; output is currently directed to stderr unconditionally.

This commit backports Anton Kovalenko's Windows-specific odxprint to
POSIX and integrates it with FSHOW.

win32-os.c: Split up handle_exception

In preparation for various changes to exception handling, split up
handle_exception into separate functions for each kind of exception.

This change is entirely cosmetic in nature.

add SSE instructions with two opcode bytes

This patch just introduces the formats, some helper functions, and most
of, if not all of, the xmm-xmm/mem ones. There's still quite some
interesting instructions left to add.

Reading floats with large exponents no longer takes too much time.

Reading 1.0s1000000000000000 will attempt to construct a very large
bignum, which takes a considerable amount of time just to report in
the end that it cannot be represented as a float. Truncate the
exponent to manageable size before raising it.

Fixes lp#309070. Thanks to Paul Khuong for the help.
