Andreas Kling 9e468579ce LibJS/Bytecode: Use malloc instead of mmap for BasicBlock buffers ...

Using mmap was quite punishing on inputs with lots of basic blocks,
such as test262 tests with eval() in a loop that goes 64k times..

~27% speed-up on language/literals/regexp/S7.8.5_A2.1_T2.js but
presumably everything everywhere will benefit from this. :^)
