[JSC] Use probe instead of debugCall for speculation failure dump
https://bugs.webkit.org/show_bug.cgi?id=259810
rdar://113365827
Reviewed by Mark Lam.
debugCall is now leveraged even in FTL, but this does not work well for FTL
since it does not restore all registers used by FTL.
In this patch, we remove debugCall, and instead we use JIT probe. This is
cleaner, fixing FTL issue, and it is OK for debug purpose calls.
