1b275a17 - [flang] -fno-integrated-as: set DisableIntegratedAS (#191346)

[flang] -fno-integrated-as: set DisableIntegratedAS (#191346) https://reviews.llvm.org/D124669 added -fno-integrated-as driver option but not the fc1 option. As a result, the backend kept MCAsmInfo::useIntegratedAssembler() set and emitted LLVM-only directives such as `.prefalign` (https://github.com/llvm/llvm-project/pull/155529), which GNU as rejects: ``` a.s: Assembler messages: a.s: Error: unknown pseudo-op: `.prefalign' ``` Follow clang and introduce fc1 -no-integrated-as to set `CodeGenOpts.DisableIntegratedAS` and llvm::TargetOptions::DisableIntegratedAS.
