    Switch to LLVM version 3.7
    
    Before this commit, GHC only supported LLVM 3.6. Now it only supports
    LLVM 3.7 which was released in August 2015. LLVM version 3.6 and earlier
    do not work on AArch64/Arm64, but 3.7 does.
    
    Also:
    * Add CC_Ghc constructor to LlvmCallConvention.
    * Replace `maxSupportLlvmVersion`/`minSupportLlvmVersion` with
      a single `supportedLlvmVersion` variable.
    * Get `supportedLlvmVersion` from version specified in configure.ac.
    * Drop llvmVersion field from DynFlags (no longer needed because only
      one version is supported).
    
    Test Plan: Validate on x86_64 and arm
