Reduce memory usage by halving the materialization threshold.
Also, functions declared with __attribute__((always_inline)) MUST be
inlined.
Note that FunctionInlining uses a heuristic to inline direct function
calls to small functions. Function size (computed by # of basic blocks
* some factors) < Inlining-threshold will be inlined.
But invoke* insn should be inlined by other means anyway.
