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.
This allows to define the offsets for each field instead
of relying on the calculated ones - useful when struct might
be defined differently across platforms.
For detecting and debugging accidental dependencies on hash-table
order, it might be helpful to invert the order at the lowest level. To
do that, uncomment `#define REVERSE_HASH_TABLE_ORDER` in "hash.c".
Racket has a minimal support to read and write `extflonum`s when the `exflonums`
are not available. In this configuration they use a different path code, so it's
necessary to test this version of the code too.
If the selector is itself a chaperone, then doing the access once
will mean that the saved result is not `chaperone-of?` the result
of doing the access a second time, at least in some cases (such as
when the accessor uses vector contracts).
Thanks to Neil T for initial spotting, and to Robby for actually
finding the bug and suggesting the fix.
The macro expander formerly put all lifted requires at the start of a
module, but that doesn't work with re-expansion if a module has
submodules and lifted requires that refer to submodules. Put lifted
submodules in the right place, instead: just before the form whose
expansion added the lifted require.
