    Various dtoa.c cleanups.  1. Despagghetify _Py_dg_strtod parsing code
    and exit points.  2. Simplify bigcomp comparison loop.  3. Don't set
    ERANGE on _Py_dg_strtod underflow (it was set inconsistently anyway).
    4. Remove unused dsign field from BCinfo struct.

    Issue #7632: When Py_USING_MEMORY_DEBUGGER is defined, disable the
    private memory allocation scheme in dtoa.c, along with a piece of code
    that caches powers of 5 for future use.  This makes it easier to
    detect dtoa.c memory leaks with Valgrind or similar tools.

    Patch by Stefan Krah.

Mark Dickinson b08a53a99d Issue #1580: use short float repr where possible.
- incorporate and adapt David Gay's dtoa and strtod
   into the Python core
 - on platforms where we can use Gay's code (almost
   all!), repr(float) is based on the shortest
   sequence of decimal digits that rounds correctly.
 - add sys.float_repr_style attribute to indicate
   whether we're using Gay's code or not
 - add autoconf magic to detect and enable SSE2
   instructions on x86/gcc
 - slight change to repr and str:  repr switches
   to exponential notation at 1e16 instead of
   1e17, str switches at 1e11 instead of 1e12
