Add general support in the function parser for "integer functions" (actually implemented as special unary operators, then wrapped in macros) and implement a family of integer logarithms. The only difference is the behavior on a non-power-of-two argument: ilog2[e] -- throw an error ilog2w -- throw a warning ilog2f -- round down to power of 2 ilog2c -- round up to power of 2 This is useful for back-converting from masks to bit values.
