Defines two pseudo-platforms for ARM and Thumb-2 instruction set.
​https://bugs.webkit.org/show_bug.cgi?id=29122

Introduces WTF_PLATFORM_ARM_TRADITIONAL and WTF_PLATFORM_ARM_THUMB2
macros on ARM platforms. The PLATFORM(ARM_THUMB2) should be used
when Thumb-2 instruction set is the required target. The
PLATFORM(ARM_TRADITIONAL) is for generic ARM instruction set. In
case where the code is common the PLATFORM(ARM) have to be used.
