Change uses of _"foo" to (intl:gettext "foo").  This is because slime
may get confused with source locations if the reader macros are
installed.

Merge intl-branch 2010-03-18 to HEAD.  To build, you need to use
boot-2010-02-1 as the bootstrap file.  You should probably also use
the new -P option for build.sh to generate and update the po files
while building.

Changes since 1.28: +43 -2 lines

Reworking of the values-type system to overcome a number of inconsistencies
causing problems:

o Redefine coerce-to-values to convert a single value type into (values type),
  rather than the former definition (values type &rest t). A single value
  type such as fixnum is now equivalent to (values fixnum). Values-type-union
  and values-type-intersection will canonicalise values types with a
  single value such as (values fixnum) back to a single value type
  such as fixnum.

o Now when the compiler makes assertions for the first value of
  continuations that may be generating multiple values it asserts the
  type as (values type &rest t), or as (value &optional type &rest t) if
  it is not sure that the continuation does generate a value.

o Enhance the type check generation to better handle the now common
  values types with optional and rest arguments. Add the new function
  Values-types-asserted which converts asserted optional and rest
  arguments to required arguments that have been proven to be delivered,
  Thus an assertion such as (values &optional fixnum &rest t) will
  generate a fixnum type check if the proven type if (values t).

o The compiler is now far more likely to pickup attempts to use an
  assertion to select a subset of values. For example
  (the (values fixnum) (values x y)) will generated a compiler warning.

o Update single values type assertions where appropriate to clarify that
  the received values may be optional or that multiple values may be
  received. For example, a macro argument which had been asserted to be
  a list via (the list ,...) would now be asserted to be
  (the (values &optional list &rest t)) etc.

o Have the IR1 translator for THE convert single value types into
  (values &optional type &rest t) so that code such as
  (the fixnum (values x y)) will still work acceptably. This does not
  restrict the possible type assertions as the values types may be used
  and are not modified.

o Recheck the asserted against the proven type for each type in a
  values-type, because the continuation is flagged for a type check
  if any of the types needs to be checked and some may not need checking.

o Split the function no-function-values-types out into a call to values-type
  followed by the new function no-function-types as this later functionality
  is useful on its own.

Implement a specializing CONS class as per issue CONS-TYPE-SPECIFIER:ADD.
The new cons-type which maintains the specialised CAR and CDR types:

o Typep recurses, checking the respective car and cdr specialisations;
  two cons-types are type= if both their car and cdr types are type=.

o Subtypep recurses, applying subtypep to the respective car and
  cdr types. If both sub-tests return true then the cons test returns
  true with a win only when both sub-tests win. If either sub-test
  returns false then the cons tests returns false with a win if either
  of sub-tests win.

o Type-intersection is applied to the respective car and cdr types,
  and wins if both win.

o The type-union of two cons-types handles cases for which either the
  respective car or cdr types are type=, in which case type-union is
  applied to the other type. This avoid returning an overly general result.

o Ctype-of a cons object simply returns (cons * *); and does not attempt
  to recurse.

o The compiler recursively checks the specialised type of the cons-type,
  which allows it to also use this type information to derive the result
  type car and cdr. Inline code is currently only generated when
  natively compiling.

Force type check conversion of continuations that may be forced to
unknown values even though they are really fixed-values (and people
might be depending on the check, like non-local RETURN-FROM.)
Don't do an inline type check for the argument of a full call, even when
we are "sure" that there is an error, since the user might want to
fix the problem by redefining the callee, and not by changing the 
caller (or callers.)
Spiffed up type error warnings to use the variable we are binding to
as context when doing a local call.  Also, instead of saying we
"got NIL", we say we got an expression that didn't return.
Changed type error checking to consistently flame about all losing
uses of a continuation, instead of maybe only flaming about the
first one, or even totally missing it if the first use we see is
non-erroneous but hairy.
Also, don't do type warnings on continuations with :DELETE TYPE-CHECK,
since those are the result of hairy type checks.

Oops...  We can't negate a check and weaken it too.  Choose whichever is
cheaper.

Changed PROBABLE-TYPE-CHECK-P to return T when we are unable to determine when
VALID-FUNCTION-USE is unable to determine the whether the template applies.  If
the VOP operand is unrestrictive, but we know it is of an unknown type, then
the type-operation will fail but the template can still be selected, since
PRIMITIVE-TYPE isn't fooled.

Changed type check weakening not to choose supertypes that are union types
(i.e. COMMON).  Also, we don't preserve the original check just because there
was some supertype predicate.

Added type check weakening (conditional on policy), and made type checks
be totally flushed only when safety = 0.
Also, when printing a type warning, check to see if the losing value is
a constant, and if so, print it instead of its type.
