  [clang-tidy][test] Add trailing -- to suppress compile_commands.json read

This fixes some build bots if we reland D150505: specifically when using GCC to
build LLVM and then `-fno-lifetime-dse` ends up passed to compile_commands.json
and causing clang-tidy to pick up the Clang unknown option.

  [cmake] Disable GCC lifetime DSE

LLVM data structures like llvm::User and llvm::MDNode rely on
the value of object storage persisting beyond the lifetime of the
object (#24952).  This is not standard compliant and causes a runtime
crash if LLVM is built with GCC and LTO enabled (#57740).  Until
these issues are fixed, we need to disable dead store eliminations
eliminations based on object lifetime.

The previous test issues are fixed by 626849c71e85d546a004cc91866beab610222194.
