analyzer: fix uninit false +ve when returning structs
This patch fixes some false positives from
-Wanalyzer-use-of-uninitialized-value
when returning structs from functions (seen on the Linux kernel).
gcc/analyzer/ChangeLog:
* region-model.cc (region_model::on_call_pre): Always set conjured
LHS, not just for SSA names.
gcc/testsuite/ChangeLog:
* gcc.dg/analyzer/sock-1.c: New test.
* gcc.dg/analyzer/sock-2.c: New test.
