Representation of inline parameters that do depend on context function is
inlined into (i.e. known constant values of function parameters.

Conditions that are interesting for function body are collected into CONDS
vector.  They are of simple as kind of a mathematical transformation on
function parameter, T(function_param), in which the parameter occurs only
once, and other operands are IPA invariant.  The conditions are then
referred by predicates.

A simplified representation of tree node, for unary, binary and ternary
operation.  Computations on parameter are decomposed to a series of this
kind of structure.
