[PATCH 0/5] Miscellaneous speed up patches |

These patches optimize the hotspots in QEMU's "noop" build:
- patch 1: parse_file_seq / strpbrk
- patch 2: find_char_unquote
- patch 3: variable_hash_1 / variable_hash_2
- patches 4+5: handle_function
On my laptop this goes from ~15.4 seconds to ~13.0 (a 15% improvement).
(My employer has a blanket assignment on file).
Thanks,
Paolo
