[AArch64] Support execute-only LOAD segments. Summary: This adds an LLD flag to mark executable LOAD segments execute-only for AArch64 targets. In AArch64 the expectation is that code is execute-only compatible, so this just adds a linker option to enforce this. Patch by: ivanlozano (Ivan Lozano) Reviewers: srhines, echristo, peter.smith, eugenis, javed.absar, espindola, ruiu Reviewed By: ruiu Subscribers: dokyungs, emaste, arichardson, kristof.beyls, llvm-commits Differential Revision: https://reviews.llvm.org/D49456 llvm-svn: 338271

[ELF] Enforce two dashes for Flag options not supported by GNU ld (i.e. no compatibility burden) Announced on https://lists.llvm.org/pipermail/llvm-dev/2020-May/141416.html Similar to D79371, but for `multiclass B` (convenience helper for defining --foo and --no-foo) Some changed options are also used by gold, but I haven't seen their one-dash use cases outside of lld's testsuite.
