Rafael Espindola daa09d03ab Add back r222061 with a fix.
This adds back r222061, but now calls initializePAEvalPass from the correct
library to avoid link problems.

Original message:

Don't make assumptions about the name of private global variables.

Private variables are can be renamed, so it is not reliable to make
decisions on the name.

The name is also dropped by the assembler before getting to the
linker, so using the name causes a disconnect between how llvm makes a
decision (var name) and how the linker makes a decision (section it is
in).

This patch changes one case where we were looking at the variable name to use
the section instead.

Test tuning by Michael Gottesman.
