re PR other/37897 (decNumber functions break strict-aliasing rules)
PR other/37897
* decDouble.h (decDouble): Replace struct with union accessible
by more types.
* decSingle.h (decSingle): Ditto.
* decQuad.h (decQuad): Ditto.
* decNumberLocal.h (DFWORD, DFBYTE, DFWWORD): access decFloat via
new members.
* decBasic.c (decFloatCompareTotal): Avoid type-pun violation.
(decNumberCompare): Ditto.
