Subject: [PM] Remove a dead field.
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=122e67cb34614082ea5ecd88793e17b4b8c7cd93;p=oota-llvm.git

[PM] Remove a dead field.

This was dead even before I refactored how we initialized it, but my
refactoring made it trivially dead and it is now caught by a Clang
warning. This fixes the warning and should clean up the -Werror bot
failures (sorry!).
