f4dceca5dc Disable some float128 tests when running under older gcc versions - 
no point in testing for old bugs in libquadmath.

cd2bbcba5b Fix bounded variable precision cpp_int's. 
1) Removed some constexpr optimizations which were causing the code to fail to spot that truncation/overflow had occurred.
2) Change min/max code for numeric_limits to work for bounded variable precision types (this needs more work as the current code relies on being able to create a fixed-precision allocator-free type of equivalent width.
3) Add tests for bounded variable precision integers.

c0df5b6747 Change ilogb to consistently return the minimum value of the exponent type 
(which may be either narrower or wider than the int return type specified in C99).
Change transcendental code which uses ilogb for loop termination, to check for
a minimal value return to correctly handle the case that the value has gone to zero.
