Hm, the testcase in PR 24669 was fixed by adjusting x86 costs, but we still
generate offset of -4 bytes here. There are also some relevant comments in PR
27707 (dupe?).
This issue with -4 offset is annoying because code size of offsetted load insn
is huge:
f: c7 40 fc 01 00 00 00 movl $0x1,-0x4(%eax)
BTW: The issue in Comment #15 is now fixed in the testsuite.
