Rui Ueyama 1c837b5fb1 [ICF] Ignore SHF_GROUP flag when comparing two sections. 
SHF_GROUP bit doesn't make sense in executables or DSOs, so linkers are
expected to remove that bit from section flags. We did that when we create
output sections.

This patch is to do that earlier than before. Now the flag is dropped when
we instantiate input section objects.

This change improves ICF. Previously, two sections that differ only in
SHF_GROUP flag were not merged, because when the control reached ICF,
the flag was still there. Now the flag is dropped before reaching to ICF,
so the difference is ignored naturally.

This issue was found by pcc.
