Looks like, it should be removed, because there is no
such identifier exported from racket/match/gen-match
(a parameter of `define-forms` now).
Closes#808.
Use `syntax-track-origin` and 'disappeared-use properties to
communicate `require` and `provide` form bindings to tools such as
Check Syntax.

When a structure type has `prop:inpersonator-of`, follow it
when attemptng to access imperonator properties.
This change fixes a problem with `impersonate-procedure` as
reported by Scott Moore.
The compiler/expander attempted to clear out references in a namespace
used only during macro expansion, but it's possible for references to
be retained (via unusual macros), so get rid of the broken attempt to
help the GC.
Since a module path index is being generated, a module path index
for the referencing module can be used, too, preserving relative
references for as long as possible.
Gustavo's tests in de3fa9a855 illustrate the problem. The solution
is simply passing 1 for `optimized_rator` to optimize_for_inline().
Additional changes generalize optimize_for_inline() a little (although
that generality doesn't seem to be useful at the moment) and collapse
some variables that represent the same value.
A new `--enable-ios=<sdk-path>` flag in combination with `--host=...`
sets up the right compiler options for compiling the Racket runtime
system as a framework to use in an iOS application.
I don't know whether the resulting framework actually works, but
compiling and linking is a step forward.
scheme_optimize_apply_values reduces (call-with-values gen proc)
to (#%apply-values proc gen) when recognizes proc as a procedure.
This extends the expressions that are recognized as procedures.
Instead of delaying the registration of some constants until a
group of expressions is re-optimized, add constant information as
it is discovered, which can expose some additional optimizations.
The old grouping was probably aimed at avoiding excessive code growth,
but I think that other and better controls are now in place. The
overall size of ".zo" files in an installation did not grow
significantly with this change.

When repoting an error during compilation, always show the path to the
module being compiled. That path was sometimes available in the error
message anyway, due to source locations for syntax errors, but often
there would be no path due to run-time errors in macros, a lack of
source locations on macro-introduced forms, etc.
The `raco setup` improvements rely on new machinery in `compiler/cm`,
and `raco make` inherits that machinery.
The parallel and non-parallel variants of `raco setup` reported
excpetions in slightly different formats, and now they're consistent.
The initial report of an exception now always shows an evaluation
context, while the summary's repeat of the error omits the context.
