- zero?, fxzero?, positive?, fxpositive?, etc., now go through
(a suitably modified) relop-length so that, for example,
(zero? (length x)) results in the same code as (null? x). added
correctness tests for these and all of the other predicates that
go through relop-length.
cpnanopass.ss, 5_2.ms
- assertion-violationf and friends now show the who, message, and
irritants in the original call when who or message is found not to
be of the right type.

original commit: 9cdc8733cbde4046fd404eefbca6433aabebcef9
Add optional beginning-line and beginning-column components to a
source object, so that line and column information can be recorded
independent of the file. Add `locate-source-object-source` to use
the recorded information. Add a cache for `locate-source` as enabled by
the `use-cache?` optional argument, which can avoid compilation times
that are quadratic in the number of `let-values` or `define-values`
forms.

obviated scale_float in the process.
number.c,
ieee.ms
- fixed 0eNNNN for large NNNN to produce 0.0 rather than infinity
strnum.ss,
5_3.ms
- the reader now raises an exception with condition type implementation
restriction (among the other usual lexical condition types), and
string->number now raises #f, for #e<m>@<a>, where <m> and <a> are
nonzero integers, since Chez Scheme can't represent polar numbers other
than 0@<a> and <m>@0 exactly. <m>@<a> still produces an inexact result,
i.e., we're still extending the set of inexact numeric constants beyond
what R6RS dictates. doing this required a rework of $str->num, which
turned into a fairly extensive rewrite that fixed up a few other minor
issues (like r6rs:string->number improperly allowing 1/2e10) and
eliminated the need for consumers to call $str->num twice in cases
where it actually produces a number. added some related new tests,
including several found lacking by profiling. added a couple of
checks to number->string whose absence was causing argument errors to
be reported by other routines.

- added pdtml flag, which if set to t causes profile-dump-html to be
called at the end of a mat run.
