This is the patch that introduced the regression (yeah, I know,
this information probably isn't the least bit useful):

Merge new ia32 backend from the branch!
* i386.h, i386.c, i386.md, reg-stack.c, i386/unix.h: Many
changes.
See ChangeLog.P2 on new_ia32_branch for details.
* rtl.h (stack_regs_mentioned_p): Delete prototype.
* i386/cygwin.h (SUBTARGET_PROLOGUE): No more do_rtl.
* i386/win32.h (SUBTARGET_PROLOGUE): Likewise.
* i386/gas.h (ASM_FILE_START): Define.
* i386/winnt.c (i386_pe_valid_decl_attribute_p): Update
for name change of ix86_valid_decl_attribute_p.
(i386_pe_valid_type_attribute_p): Similarly.
The hunt used Volker's reduced testcase with -march=i686 on
i686-pc-linux-gnu.
