Revert "This patch causes clang to reject alias attributes that point to undefined names. For example, with this patch we now reject"
This reverts commit r193161.
It broke
void foo() __attribute__((alias("bar")));
void bar() {}
void zed() __attribute__((alias("foo")));
Looks like we have to fix pr17639 first :-(
