I would be heavily surprised if it did, esp. since Linux is GCC's bread and butter. Esp. with the GCC 4.5.x (and newer) plugin architecture (e.g. DragonEgg), there's no need, it can already use LLVM (allegedly, though I haven't tried).

586-only instructions are very very rare from compilers. You're more likely to see 686 (CMOV..) or SSE2 (XMM) than anything else.
