Use a cache to remember tail calls that were already implemented and replace further implementations of the same tail call with a jump to the previous implementation. Coverage shows that all cases are covered in libs/estdlib/src and libs/jit/src: OP_RETURN: 50 misses, 1735 hits (97%) OP_JUMP/OP_CALL_LAST/OP_CALL_ONLY: 656 misses, 389 hits (37%) OP_CALL_LAST: 220 misses, 206 hits (48%) OP_FUNC_INFO: 58 misses, 1619 hits (97%) Signed-off-by: Paul Guyot <[email protected]>

This is required as flash chips are programmed by setting bits from 1 to 0, and erased by setting all bits to 0, so placeholders set to FF can be replaced without erasing a whole block. Signed-off-by: Paul Guyot <[email protected]>

Add a new `term_reuse_binary` to reuse a refc binary, taking advantage of private_append compiler optimization. Add handling of out of memory errors in term_alloc_refc_binary by raising out of memory error instead of aborting. Update `and_/3` signature in JIT backends to handle and with a new register, and performed few optimizations accordingly by removing unnecessary copy. Signed-off-by: Paul Guyot <[email protected]>
