* module/language/tree-il/analyze.scm: Break analyzer out into its own
file.
* module/language/tree-il/compile-glil.scm: Port the GHIL->GLIL compiler
over to work on tree-il. Works, but still misses a number of important
optimizations.
* module/language/tree-il.scm: Add <void>. Not used quite yet.
* module/language/glil.scm: Remove <glil-argument>, as it is the same as
<glil-local> (minus an offset).
* module/language/glil/compile-assembly.scm:
* module/language/glil/decompile-assembly.scm:
* module/language/ghil/compile-glil.scm: Adapt for <glil-argument>
* removal.
* module/Makefile.am (TREE_IL_LANG_SOURCES): Reorder, and add
analyze.scm.
* module/language/ghil/compile-glil.scm (codegen): Push a program's
source locations before copying external args to heap -- perhaps fixes
(program-source p 0) for some programs.
* module/language/glil/decompile-assembly.scm (decompile-load-program):
Take another arg, the object vector. Emit <glil-bind> and <glil-unbind>
correctly. Properly unparse properties. Just have to deal with source
locations now.
* module/language/glil/decompile-assembly.scm: A first pass at an
assembly->glil decompiler. Works for a small subset of programs.
* module/Makefile.am (GLIL_LANG_SOURCES):
* module/language/glil/spec.scm (glil): Add the decompiler.
