cached t-functions and inferred ASTs need to be cleared at

before doing inlining, to prevent infinite recursion.
for example, consider this function:
> (x::Real, y::Real) = (y < x)
after doing inference on this >, we cache its AST "(y < x)".
now we begin inlining. the problem is that the inlining code
itself will trigger compilation of functions that use >, so
"(y < x)" will be inlined into those functions. ultimately
we inline the definition of < into "(y < x)", but by then it's
too late, since "(y < x)" has already been inlined into some
functions.
to fix this, we clear the t-function cache after all
type-inference related code has been compiled. now we can
inline everything fully without compilation of the compiler
itself interfering.
