fix#389 (apply doesn't throw exception when last argument isn't a list)
fold-primref and fold-primref2 ignored app-convention when
attempting to fold certain primitive calls in 'test and 'effect
context and when falling back on the default primitive handler.
We now residualize primitive references if the app-convention
is not 'call. The original fold-primref2 already bypassed the
inline handler when the app-convention was not 'call.

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

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.

arguments. cp0 optimizes away a number of additional equality
operations at optimize-level 3 (including bytevector=?) when
applied to the same variable references, as it already did for
eq?, eqv?, and equal?, at all optimize levels.
