d8d4b76917 fix precision on reading with large exponents 
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).

b78838a641 cp0: move only known-single-valued out of single-value context 
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.

aaaa5fefa1 add compute-size-increments 
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`.

61df2f25f7 fix for issue #343 
- the compiler now uses a temporary variable to hold the return
  value of a nested call across the restore-local-saves form to
  properly handle the case where the destination lvalue is an mref
  whose base and/or index is a local save.
