[clang][Arm] Fix handling of -Wa,-implicit-it= Similiar to D95872, this flag can be set for the assembler directly. Move validation code into a reusable helper function.

[clang] Don't pass multiple backend options if mixing -mimplicit-it and -Wa,-mimplicit-it If multiple instances of the -arm-implicit-it option is passed to the backend, it errors out. Also fix cases where there are multiple -Wa,-mimplicit-it; the existing tests indicate that the last one specified takes effect, while in practice it passed double options, which didn't work as intended.

Revert "[Driver] Delete -mimplicit-it=" This reverts commit 2919222d8017f2425a85765b95e4b7c6f8e70ca4. That commit broke backwards compatibility. Additionally, the replacement, -Wa,-mimplicit-it, isn't yet supported by any stable release of Clang. See D102812 for a fix for the error cases when callers specify both -mimplicit-it and -Wa,-mimplicit-it.
