asan: Do not call asan_function_start () without the current function [PR113251]
Using ASAN on i686-linux with -fPIC causes an ICE, because when
pc_thunks are generated, there is no current function anymore, but
asan_function_start () expects one.
Fix by not calling asan_function_start () without one.
A narrower fix would be to temporarily disable ASAN around pc_thunk
generation. However, the issue looks generic enough, and may affect
less often tested configurations, so go for a broader fix.
