Accept negative inputs to -2^63 for dec2bin and dec2hex (bug #63089)
dec2bin.m: Accept negative inputs lower than -flintmax down to -2^63
Return 64-bit string in certain cases for Matlab compatibility
Activate BISTs commented out earlier
dec2hex.m: Remove repeated code and call dec2bin instead
Accept negative inputs lower than -flintmax down to -2^63
Update and activate BISTs commented out earlier
