Recommit 116056, now with the missing file... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@116083 91177308-0d34-0410-b5e6-96231b3b80d8

Target/X86: Add explicit Win64 and System V/x86-64 calling conventions. Summary: This patch adds explicit calling convention types for the Win64 and System V/x86-64 ABIs. This allows code to override the default, and use the Win64 convention on a target that wants to use SysV (and vice-versa). This is needed to implement the `ms_abi` and `sysv_abi` GNU attributes.
