Syntax objects have "source" field

Browse source 
* libguile/syntax.c (scm_make_syntax): Add optional "source" argument.
  Note that this function is internal.
  (scm_syntax_source): New function, replacing definition in boot-9.scm.
* libguile/syntax.h: Add new declarations.
* module/ice-9/psyntax-pp.scm:
* module/ice-9/psyntax.scm (source-annotation): For syntax objects, the
  source annotation comes direct from the syntax object.
* module/system/vm/assembler.scm (link-data, intern-constant): Write
  5-word syntax objects.
