f19bae413c Add support for Intel Skylake and Intel Broadwell PMC's. The Broadwell PMC's have been
tested on the Broadwell-Xeon with a hacked up version of pmcstudy -T. I still need
to circle back and add in to pmcstudy all the new tests from the Broadwell Vtune
guide (for the hacked up version I just made it so I could run the -T option). The
Skylake CPU is not yet available (even though Intel is advertising it .. imagine that).
The Skylake PMC's will need to be tested once we can get a sample skylake CPU :-)

7b3ea376a2 META MODE: Prefer INSTALL=tools/install.sh to lessen the need for xinstall.host.
This both avoids some dependencies on xinstall.host and allows
bootstrapping on older releases to work due to lack of at least 'install -l'
support.

e64ba55dd2 Change the driver stats to what they really are: unsigned values.
When pmcstat exits after some samples were dropped, give the user an
idea of how many were lost. (Granted, these are global numbers, but
they may still help quantify the scope of the loss.)

ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

a745246822 Implement hwpmc(4) for Freescale e500 core.
This supports e500v1, e500v2, and e500mc. Tested only on e500v2, but the
performance counters are identical across all, with e500mc having some
additional events.

f6e6460dfc Add support for the MIPS74K SoC family performance counters events.
These are similar to the mips24k performance counters - some are
available on perfcnt0/3, some are available on perfcnt1/4.
However, the events aren't all the same.

* Add the events, named the same as from Linux oprofile.
* Verify they're the same as  "MIPS32(R) 74KTM Processor Core Family
  Software User's Manual"; Document Number: MD00519; Revision 01.05.
* Rename INSTRUCTIONS to something else, so it doesn't clash with
  the alias INSTRUCTIONS.  I'll try to tidy this up later; there
  are a few other aliases to add and shuffle around.

Tested:

* QCA9558 SoC (AP135 board) - MIPS74Kc core (no FPU.)
* make universe; where it didn't fail for other reasons.

TODO:

* It'd be nice to support the four performance counters
  in at least this hardware, rather than just two.

bc0ad9a99d Fix Ivy Bridge+ MEM_UOPS_RETIRED counters
The MEM_UOPS_RETIRED actually work the same way as the Sandy
Bridge counters, but the counters were documented in a different
way and that seemed to cause the Ivy Bridge counters to be
implemented incorrectly.  Use the same counter definitions as
Sandy Bridge.  While I'm here, rename the counters to match
what's documented in the datasheet.

9e60f3acd2 Fix Sandy Bridge+ hwpmc branch counters
On Sandy Bridge and later, to count branch-related events you
have to or together a mask indicating the type of branch
instruction to count (e.g. direct jump, branch, etc) and a bits
indicating whether to count taken and not-taken branches.  The
current counter definitions where defining this bits individually,
so the counters never worked and always just counted 0.

Fix the counter definitions to instead contain the proper
combination of masks.  Also update the man pages to reflect the
new counters.

d95b3509e1 Update the hwpmc driver to have the new type HASWELL_XEON. Also
go back through HASWELL, IVY_BRIDGE, IVY_BRIDGE_XEON and SANDY_BRIDGE
to straighten out all the missing PMCs. We also add a new pmc tool
pmcstudy, this allows one to run the various formulas from
the documents "Using Intel Vtune Amplifier XE on XXX Generation platforms" for
IB/SB and Haswell. The tool also allows one to postulate your own
formulas with any of the various PMC's. At some point I will enahance
this to work with Brendan Gregg's flame-graphs so we can flamegraph
various PMC interactions. Note the manual page also needs some
work (lots of work) but gnn has committed to help me with that ;-)

49fe48ab0c For Xeon 7500 and 48XX (Nehalem EX and Westmere EX) variants of the
Core i7 and Westmere processors, the uncore PMC subsystem is
completely different from the uncore PMC on smaller versions of CPUs.
Disable existing uncore hwpmc code for EX, otherwise non-existing MSRs
are accessed.

The cores PMCs seems to be identical for non-EX and EX, according to
the SDM.

169dd953b0 Add hwpmc(4) support for the PowerPC 970 class processors, direct events.
This also fixes asserts on removal of the module for the mpc74xx.

The PowerPC 970 processors have two different types of events: direct events
and indirect events.  Thus far only direct events are supported.  I included
some documentation in the driver on how indirect events work, but support is
for the future.
