Re-enable B3 hoistLoopInvariantValues
https://bugs.webkit.org/show_bug.cgi?id=212651
rdar://132334359
Reviewed by Yijia Huang and Yusuke Suzuki.
Re-enables the hoistLoopInvariantValues phase in B3. This was
previously disabled due to (as I understand it) performance
concerns, but recent benchmarking shows it as neutral, if not
a slight progression on Speedometer 3. LICM in B3 specifically
is also more relevant now that WASM is more common - JS isn't
likely to benefit quite as much since we already do LICM in
DFG. But WASM, targeting B3 directly, is currently missing out
on this important optimization.
