https://bugs.webkit.org/show_bug.cgi?id=196488

Reviewed by Carlos Garcia Campos.

.:

* Source/cmake/DetectSSE2.cmake: Added.
* Source/cmake/WebKitCompilerFlags.cmake: Detect SSE2 support and
add SSE2 to the global compiler flags.

Source/JavaScriptCore:

* assembler/MacroAssemblerX86Common.cpp: Remove unnecessary (and
incorrect) static_assert.
(JSC::MacroAssemblerX86Common::collectCPUFeatures):
* assembler/MacroAssemblerX86Common.h: Remove SSE2 flags.

Tools:

* Scripts/webkitdirs.pm:
(generateBuildSystemFromCMakeProject): Do not add SSE2 flags here
for x86 builds. This is now handled in WebKitCompilerFlags.cmake.
