LLVM 3.6 is broken on AArch64/Arm64 and LLVM 3.7 was released in August.

I already have git master building with LLVM-3.7 on x86_64/linux and can test on numerous others.

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.

* Add CC_Ghc constructor to LlvmCallConvention.
* Replace `maxSupportLlvmVersion`/`minSupportLlvmVersion` with
  a single `supportedLlvmVersion` variable.
* Get `supportedLlvmVersion` from version specified in
* Drop llvmVersion field from DynFlags (no longer needed because only
  one version is supported).

Test Plan: Validate on x86_64 and arm
