Revert a part of the `d' constraint documentation update made with
commit 111868 ("Use define_constraint for MIPS"),
<https://gcc.gnu.org/ml/gcc-patches/2006-03/msg00460.html>,
<https://gcc.gnu.org/ml/gcc-patches/2006-03/msg00541.html>, which
inadvertently made the registers covered to be referred to as "address"
rather than "general-purpose" registers, and then further clarify the
set of registers allowed with MIPS16 code.

The test has a bunch of hardcoded integer literals that would fit only in a
32 bits+ int, causing overflow warnings for a 16 bit int target like avr.
