Add a parameter to constrain the compiler (off by default) to
implement `+`, `*`, and variants as left-associative when given
multiple arguments.

Make the recent changes insensitive to whether `/` produces
an exact value when its first argument is an exact 0.

A large-magnitude mantissa can cancel some of the magnitude of an
exponent.
Also, make numbers like 1/0e1 be divide-by-zero parse errors
instead of +inf.0 (like 1/0, and in contract to 1/0# or 1/0#e1).

In safe compilation modes, avoid turning an error like
(let ([x (values 1 2)]) x)
or
(car (list (values 1 2)))
into a program that returns multiple values or
(if (list (values 1 2)) 3 4)
into a program that returns without an error.
In addition, refrain from moving an expression from a non-tail
position within a procedure to a tail position, unless the expression
is not only single valued but also gauarnteed not to inspect the
immediate continuation (e.g., using `call/cc` and comparing the result
to a previously captured continuation). This constraint applies even
in unsafe compilation modes, because the intent it to provide some
guarantees about non-tail positions to complement existing guarantees
of tail positions.

Also adds `get-initial-thread`, since threa values are useful with
`compute-size[-increments]`.
Changes the compiler to inline `weak-pair?` and `ephemeron-pair?`,
since that provides better performance for `compute-size-increments`.

When writing a fasl stream, add extra graph points as needed
to limit recursive reading to about 500 non-tail recursions.

Use `vfasl-convert-file` to convert to the vfasl format, something
like this:
(vfasl-convert-file "orig/petite.boot" "new/petite.boot" '())
(vfasl-convert-file "orig/scheme.boot" "new/scheme.boot" '("petite"))
(vfasl-convert-file "orig/racket.boot" "new/racket.boot" '("petite" "scheme"))

Also, for completeness, correct the listing of callee-save registers
in callable return for x86 & x86_64.

When a record-type constructor is formed dynamically,
and when it had more than 6 arguments, use a wrapper
to explicitly set the constructor's arity.
