[JSC] Drop ARM_TRADITIONAL support in LLInt, baseline JIT, and DFG
​https://bugs.webkit.org/show_bug.cgi?id=191675

Reviewed by Mark Lam.

Source/JavaScriptCore:

We no longer maintain ARM_TRADITIONAL LLInt and JIT in JSC. This architecture will use
CLoop instead. This patch removes ARM_TRADITIONAL support in LLInt and JIT.

Discussed in ​https://lists.webkit.org/pipermail/webkit-dev/2018-October/030220.html.
