[PATCH] D86510: [compiler-rt] Fix atomic support functions on 32-bit architectures

[Eli Friedman via Phabricator via llvm-commits]

> This problem was found while compiling atomic.c for MIPS32 since the -Watomic-alignment warning was being triggered and objdump showed an undefined reference to _atomic_is_lock_free.

Are you sure this fixes the issue properly?  If we're triggering -Watomic-alignment, probably the types are wrong somewhere.  (In particular, some targets support lock-free operations on `_Atomic long long`, but the ABI alignment of `long long` is lower than 8.)
