Fix modref's iteraction with store mergingreleases/gcc-14
Hi,
this patch fixes wrong code in case store-merging introduces load of function
parameter that was previously write-only (which happens for bitfields).
Without this, the whole store-merged area is consdered to be killed.
PR ipa/111613
gcc/ChangeLog:
* ipa-modref.cc (analyze_parms): Do not preserve EAF_NO_DIRECT_READ and
EAF_NO_INDIRECT_READ from past flags.
