-----------
[JSC] Remove op_rest_length
https://bugs.webkit.org/show_bug.cgi?id=307028
rdar://169675925
Reviewed by Yusuke Suzuki.
After 306822@main op_create_rest computes the rest the length on it's
own in DFG so we no longer need the separate length computation bytecode.
This patch updates LLInt/Baseline to also compute the length for rest
Arrays internally rather than via op_rest_length and removes
op_rest_length.
No new tests, no behavior change. Covered by existing tests.
