[JSC] reading scratch-buffer is not pure-function call
https://bugs.webkit.org/show_bug.cgi?id=248453
rdar://102120764
Reviewed by Mark Lam.
We should not use callWithoutSideEffects for
operationArithMinMultipleDouble / operationArithMaxMultipleDouble
calls since they read ScratchBuffer memory, thus they are not pure
functions. They depend on content of ScratchBuffer.
So, even if ScratchBuffer's address is the same, then the result depends on
its content. Use vmCall instead.
