VAX: test changes for VAX floats
The hexfp (literals or %a) seems to be partially working: simple cases
seem to work, but there are failures.

VAX: code changes for VAX floats
Mainly to avoid Inf and NaN, which VAX does does not have.
There is something like Inf called "excess" but that is
a deadly exception, seems to manifest itself in vax-netbsd
either as a SIGFPE or SIGSEGV (pretty much untrappable at
least from Perl level).
The range of VAX floats is different from IEEE.
There is positive zero, but no negative zero.

VAX: Configure changes for VAX floats
Detect the VAX floating point formats D and G.
And the F float, but that is float (duh), never likely to be
the double, but do it for consistency (we detect IEEE single
precision floats, too).
The T float and X float are the IEEE 64-bit and 128-bit,
but those were available only on the Alpha.
Tested on vax-netbsd.
