When the unoptimized code of a function exceeds 1 MB, start its optimized compile with far_branch_level=1 instead of 0. Without this, the assembler fails on out-of-range conditional branches at level=0, longjmps out of the optimizing pipeline, and the whole pipeline reruns at level=1 from scratch. Measured on a naive 49 KLOC generated lexer with --huge_method_cutoff gates lifted: JIT compile drops from ~26.6s to ~13.2s (about 50%).
