check for proper llvm version

I have mesa today's snapshot build against llvm 3.9.1.

When glxgears is started it aborts with the message:

LLVM ERROR: Cannot select: intrinsic %llvm.amdgcn.buffer.load.format

It looks like this intrinsic is supported with llvm 4.0 and higher, as when
mesa is build against llvm 4.0 apps work as expected.

A simple patch to fix this error is attached.
