; Check that lli respects alignment on global variables.
;
; Returns ((uint32_t)&B & 0x7) - A + C. Variables A and C have byte-alignment,
; and are intended to increase the chance of misalignment, but don't contribute
; to the result, since they have the same initial value.
;
; A failure may indicate a problem with alignment handling in the JIT linker or
; JIT memory manager.
