Remove runtime detection of Neon on ARM CPUs
Now the only way to enable Neon support is to change the mkspec.
[ChangeLog][Important Behavior Changes] Qt no longer checks for
support for the Neon FPU on ARM platforms at runtime. Code optimized
for Neon must be enabled unconditionally at compile time by ensuring
the compiler supports Neon. You may need to edit your mkspec for that.
