a12ca2b999 multiple languages support via file extension or #lang header
From scripts/compile pushed default assumption of #:from as 'scheme down
into system/base/compile where filename and first line can be used to
deduce intended "from" language.  If first line of a file is of the form
  #lang ecmascript
then the file is assumed consist of source language "ecmascript".

* module/scripts/compile.scm (compile): changed default #:from to #f
  from 'scheme

* module/system/base/compile.scm(lang-from-port, %file-extension-map,
  add-lang-extension, lang-extension-for): added global
  %file-extension-map with accessor lang-extension-for and updater
  add-lang-extension.  Also, added lang-from-port to parse  first line,
  looking for #lang.

* test-suite/tests.scm: added "load-lang" test.

* test-suite/Makefile.am(SCM_TESTS): added tests/load-lang.test

eb5ecf4944 Properly display locations in "source vector" form.

4456245753 Add missing #:modules argument for coverage-data->lcov.
The code coverage function `coverage-data->lcov` has a documented
`modules` argument, however that was missing from the source. I have
added it so when supplied it only converts the coverage data for the
supplied modules. If not supplied it defaults the old behavour of
including all the modules currently loaded.

* module/system/vm/coverage.scm (coverage-data->lcov): Add #:modules
parameter and honor it.

e4e8afd6c8 Allow empty vendor string in GNU target triplets.
NetBSD and pkgsrc have been using an empty vendor string since the
mid-'90s, such as x86_64--netbsd.  pkgsrc has been carrying around a
workaround just the guile build for a long time.  (Before that,
NetBSD omitted the vendor altogether, so if x86_64 existed then it
might have been `x86_64-netbsd', but that caused more problems.)
This change makes Guile accept an empty vendor string so workarounds
are no longer necessary.

* module/system/base/target.scm (validate-target): Allow empty vendor
string in GNU target triplets.
* test-suite/tests/cross-compilation.test ("cross-compilation"): Add
tests for "x86_64--netbsd".

d238566d0e CPS compiler reduces eq? on constant to eq-constant?
* module/language/cps/compile-bytecode.scm (compile-function): Expect
  eq-constant? instead of eq-null?, etc.
* module/language/cps/effects-analysis.scm: Likewise.
* module/language/cps/reify-primitives.scm (reify-primitives): For
  eq-constant?, reify a $const unless the constant is an immediate whose
  encoding fits in 16 bits.
* module/language/cps/type-fold.scm (materialize-constant): Helper to
  make a constant from a type, min, and max.
  (fold-eq-constant?): New helper.
  (eq-constant?): New folder.
  (undefined?): Define specifically.
  (define-nullish-predicate-folder): Renamd from
  define-special-immediate-predicate-folder.  Use only for null?, false,
  and nil?.
  (*branch-reducers*): New mechanism.  Reduce eq? to eq-constant? if
  possible.
  (local-type-fold): Refactor to use materialize-constant, and to allow
  reducing branches.
* module/language/cps/types.scm (constant-type): Return three values
  instead of a type entry.
  (constant-type-entry): New function that returns a type entry.  Adapt
  callers.
  (infer-constant-comparison): New helper.

  truncate-bits signed arg.
  (define-immediate-type-predicate): Adapt to visit-immediate-tags
  change.
* module/language/tree-il/compile-cps.scm (convert): Convert eq? to
  constant to eq-constant?.  Advantaged is that it gets fixnums and
  chars in addition to special immediates.
* module/language/tree-il/cps-primitives.scm (define-immediate-type-predicate):
  Adapt to allow #f as pred.
* module/system/base/types/internal.scm (immediate-tags): Use #f as pred
  for false, nil, etc.
  (immediate-bits->scm): Adapt.
