[clang] Add a command line flag for the Machine Function Splitter. This patch adds a command line flag for the machine function splitter (added in rG94faadaca4e1). -fsplit-machine-functions Split machine functions using profile information (x86 ELF). On other targets an error is emitted. If profile information is not provided a warning is emitted notifying the user that profile information is required. Differential Revision: https://reviews.llvm.org/D87047

[clang] Remove profile available check for fsplit-machine-functions. Enforcing a profile available check in the driver does not work with incremental LTO builds where the LTO backend invocation does not include the profile flags. At this point the profiles have already been consumed and the IR contains profile metadata. Instead we always pass through the -fsplit-machine-functions flag on user request. The pass itself contains a check to return early if no profile information is available. Differential Revision: https://reviews.llvm.org/D87943
