PATCH: Compile g++.dg/opt/pr52727.C with -march=i686 for ia32

[H.J. Lu]

Hi,

Revision 206943 caused a regression on g++.dg/opt/pr52727.C, which wasn't
caught by my automated tester since SSE2 and SSE math are enabled by
default.  This patch adds -march=i686 for ia32 when compiling
g++.dg/opt/pr52727.C, which is required to reproduce the bug. OK to
install?

Thanks.
