Doing so can deadlock when the thread already owns another vnode lock,
e.g. during a rename, as was demonstrated by the reporter. In fact,
there seems to be no need to force the call to getinoquota() always,
because vn_open() locks vnode exclusively, and this is the most
important case. To add to the point, directories where the dirent is
added or removed, are locked exclusively as well.

The atpic_register_sources callback tries to avoid registering interrupt
sources that would collide with an I/O APIC. However, the previous
implementation was failing to register IRQs 8-15 since the slave PIC
saw valid IRQs from the master and assumed an I/O APIC was present. To
fix, go back to registering all 8259A interrupt sources in one loop when
the master's register_sources method is invoked.

[CodeGen] Initialize large arrays by copying from a global
Currently, clang compiles explicit initializers for array elements
into series of store instructions. For large arrays of built-in types
this results in bloated output code and significant amount of time
spent on the instruction selection phase. This patch fixes the issue
by initializing such arrays with global constants that store the
binary image of the initializer.

The previous default of "balanced" appears to have caused pathological
behavior, including very poor performance and 100% CPU load in the
arc_reclaim_thread.
The symptoms appeared when the daily periodic run started.
With this change, the system--and the ARC in particular--behaved
normally during a manual daily periodic run.
From Mark Johnston: The port of the balanced strategy is incomplete,
since arc_prune_async() is a no-op on FreeBSD. (This also seems
to imply that r337653 is a no-op.) After 12 is branched we can
port the remaining bits and consider changing the default back.
