[RFA] testsuite/gdb.base/pointers.[c,exp]: don't assume >= 8 byte doubles

(This is a resubmission.) In pointers.c, a double D is assigned
-1.375E-123. This only fits if a double is (at least) 8 bytes. For a
4-byte double you get an underflow. The pattern matching of the
decimals when printing the value of D also assumes it's >= 8 bytes. K&R
says an acceptable minimum for FLT_MIN is 1E-37, so I decided to go with
that and relaxed the decimal pattern matching to the same level as for
floats.
Ok to commit?

* gdb.base/pointers.c: Don't assume doubles are >= 8 bytes.
* gdb.base/pointers.exp: Relax pattern match of decimals.
