Message:

Remove sh4 specific code from JavaScriptCore
​https://bugs.webkit.org/show_bug.cgi?id=166640

Reviewed by Filip Pizlo.

Source/JavaScriptCore:

sh4-specific code does not compile for a while (r189884 at least).
As nobody seems to have interest in this architecture anymore, let's
remove this dead code and thus ease the burden for JSC maintainers.
