Remove obscure & rarely used ARM intrinsics
In almost all cases it is preferable to use the stable `asm!` instead of calling these intrinsics. This PR removes the following unstable intrinsics: - `__breakpoint` Clang extension, not part of ACLE. - `brk`: undocumented - `_rev*`, `_clz*`, `_rbit*`: use methods on integer types instead - `__ldrex`, `__strex`: deprecated in ACLE, hard to use correctly - Register access API: API doesn't match ACLE, better to just use asm Also considered for deletion, but not included in this PR: - Barriers: `__isb`, `__dsb`, `__dmb` - Hints: `__wfi`, `__wfe`, `__sev`, `__sevl`, `__yield`, `__nop`
