5d0e26e5 - [compiler-rt] Make sure __clzdi2 doesn't call itself recursively on sparc64 (#136737)

[compiler-rt] Make sure __clzdi2 doesn't call itself recursively on sparc64 (#136737) On 64-bit platforms, libgcc doesn't ship with __clzsi2, so __builtin_clz gets lowered to __clzdi2. A check already exists for GCC, but as of commit 8210ca019839fc5430b3a95d7caf5c829df3232a clang also lowers __builtin_clz to __clzdi2 on sparc64. Update the check so that building __clzdi2 with clang/sparc64 also works.
