1.0.29.54.rc5: fix load-time-value regressions

* (SPECIFIIER-TYPE 'FUNCTION) is not a FUN-TYPE.

* Don't allow constant moves from LTV TNs (better fix after release):
this is the simple and obviously correct fix.

* Also declaim the type of the correct function in the test-case from
last commit.

1.0.29.54.rc3: Make float tests consume less memory

* A test introduced in 1.0.29.44 uses a lot of memory during compilation. Split
the definition into multiple toplevel functions to avoid exhausting the heap.

1.0.29.54.rc2: two more CTOR optimization issues

* Invalid calls of the form (MAKE-INSTANCE ''QUUX) or similar reported
hard to understand errors instead of using the NO-APPLICABLE-METHOD
machinery. (reported by Gabor Melis)

* Runtime generation of new CTORs for the inline cache was not thread
safe: grab *WORLD-LOCK* to ansure that (1) all CTORs end up in
*ALL-CTORS* (2) we don't construct a CTOR with the same name twice.
Also initialize the new CTOR with the initial constructor before
setting its FDEFINITION: this is strictly speaking not needed given
the lock, but more clearly correct. No test-case, as I was unable to
actually provoke problem in real code.

1.0.29.54: Inline unboxed constants on x86[-64]

* New build-time feature: inline-constants, which specifies that SB!C
and SB!VM implement a protocol described in base-target-features.lisp-expr.
Backends implementing that feature are able to load constants from code
components, in a section that follows the actual executable code.

* Implement the protocol on x86 and x86-64, and use it for float constants,
and, on x86-64 only, mid-sized (> 2^(29-32), but still machine-sized)
integers.

* Use the new feature in integer and float arithmetic VOPs.

* Adjust a few test cases to take newly consing situations into account.

* Clean-up:
- New build-time feature: float-eql-vops, which disable rewriting EQL
of single and double floats in terms of foo-float*-bits.
- Fix a typo (unused variable lookup) in TWO-ARG-+/-

1.0.29.53: some LOAD-TIME-VALUE smartness

* Implicit READ-ONLY-P for obviously immutable values.

* Annotate the result with a derived type -- in practice
the obvious declarared type of the function, if any.

* In the test suite organize compiler tests a bit:

** compiler-test-util.lisp has some general-purpose
tools for determining if the compiled code passes muster.

** Move some pure tests from compiler.impure.lisp to the pure
file: they were in the impure file because they defined
utils which are now in the COMPILER-TEST-UTIL (aka CUA)
package.

1.0.29.52: small UCD optimizations and related cleanups

* Fix "optimization failure with anything using
SB-IMPL::UCD-GENERAL-CATEGORY" reported by Lynn Quam
(https://bugs.launchpad.net/sbcl/+bug/392206) and related
performance issues.

** Declare returns types of UCD accessors where it seems to matter.

** Make the character database a global variable, not special.

* Delete stale header comments from target-char.lisp: not just ASCII
for quite a while now.

* Delete references to fonts and bits from docstrings everywhere but
in CHAR-INT and canonicalize docstring indentation.

(The patch is a bit noisy because moving the definition of the
character database inside the macrolet messed up a whole bunch of
indentation -- sorry about that.)

1.0.29.45: another CTOR optimization

* If we're forced to use the fallback generator, but the initargs can be
verified early on and there are no extra methods on MAKE-INSTANCE
we don't have to go through full MAKE-INSTANCE: instead use
FAST-MAKE-INSTANCE. 1 less GF call and no initarg checking at runtime
yields a ~2-4 fold performance improvement.

1.0.29.44: Complex float improvements

* On all platforms:
- Slightly more stable complex-complex float (double and single)
division;
- New transform for real-complex division;
- complex-real and real-complex float addition and subtraction
behave as though the real was first upgraded to a complex, thus
losing the sign of any imaginary zero.

* On x86-64
- Complexes floats are represented packed in a single SSE register;
- VOPs for all four arithmetic operations, complex-complex, but also
complex-real and real-complex, except for complex-complex and
real-complex division;
- VOPs for =, negate and conjugate of complexes (complex-real and
complex-complex);
- VOPs for EQL of floats (real and complexes).
- Full register moves for float values in SSE registers should also
speed scalar operations up.

1.0.29.41: inline CTOR caches for MAKE-INSTANCE

* If MAKE-INSTANCE has constant keywords but a variable first argument,
build an inline cache of CTORs.

** Initially a sorted list, switching to a max 256 entry table if
the list grows too large.

** Rename CTOR-NAME to CTOR-NAME-OR-CLASS, and allow building CTORs
for class arguments as wel. Similarly, CTOR function names
can contain class objects as well.

** Factor out RANDOMLY-PUNTING-LAMBDA from cache.lisp, since CTOR
cache wants it too.

** STD-INSTANCE-P and FSC-INSTANCE-P become functions with compiler
macros -- they are now used in compiler-support.lisp, which
is built before low.lisp, so using macros is out.

* Also enable the existing CTOR optimization for constant class objects
as class arguments.

* Tests.

GET-INTERNAL-REAL. Feh.

1.0.29.38: better DESCRIBE

* Rework DESCRIBE for more comprehensive reporting and
easier to read output.

* Delete src/pcl/describe.lisp, no PCL leftovers in the new DESCRIBE
except for some heritage in DESCRIBE-INSTANCE.

* Fix COMPILED timestamps: we want both internal-real and universal
time for different use-cases. (Though I'm not sure if we really care
about the COMPILED timestamps that much, especially now that I
unilaterally removed their printing from DESCRIBE.)

* Give primitive type transform functions the lambda-list of the type.
