Rollup merge of #91675 - ivanloz:memtagsan, r=nagisa
Add MemTagSanitizer Support Add support for the LLVM [MemTagSanitizer](https://llvm.org/docs/MemTagSanitizer.html). On hardware which supports it (see caveats below), the MemTagSanitizer can catch bugs similar to AddressSanitizer and HardwareAddressSanitizer, but with lower overhead. On a tag mismatch, a SIGSEGV is signaled with code SEGV_MTESERR / SEGV_MTEAERR. # Usage `-Zsanitizer=memtag -C target-feature="+mte"` # Comments/Caveats * MemTagSanitizer is only supported on AArch64 targets with hardware support * Requires `-C target-feature="+mte"` * LLVM MemTagSanitizer currently only performs stack tagging. # TODO * Tests * Example
