Revert "Merge remote-tracking branch 'slim/jb4.2' into aokp-mr2"

This reverts commit e2c44d187289dd031de6a8724179cf26925adb12, reversing
changes made to 8386ab017838c2b2f7113a8a99305a2b6bda3cd0.
Disable -Xjnigreflimit.

This was supposed to help find bugs, but in practice (unlike the
locale reference limit and the pinned array limit) doesn't. What it
does do is cause well-behaved code to fail if its allocation rate
is high. This has caused trouble for both audio and graphics code
running on eng builds.
