losing type information.
python/m5/config.py:
Allow math on CheckedInt-derived ParamValue classes w/o
losing type information.
- Make CheckedInt derive from NumericParamValue, and *not*
multiply inherit from long
- Move CheckedInt bounds check to _check() hook so we can
call it when value is updated (not just in constructor)
python/m5/convert.py:
- make toInteger() return a long, making toLong() unnecessary
- toMemorySize should return long rather than float
