This reverts commit ad36e4284d66c3609ef8675ef02ff1844bc1951d, fixing a single uninitialized bit (which cannot be detected with Address Sanitizer). This PR adds support for the llvm-mc command-line flag "--gsframe" and adds ".sframe" to the legal values passed ".cfi_section". It plumbs the option through the cfi handling code a fair amount. Code to support actual section generation follows in a future PR. These options match the gnu-assembler's support syntax for sframes, on both the command line and in assembly files. First in a series of changes that will allow llvm-mc to produce sframe .cfi sections. For more information about sframes, see https://sourceware.org/binutils/docs-2.44/sframe-spec.html and the llvm-RFC here: https://discourse.llvm.org/t/rfc-adding-sframe-support-to-llvm/86900
