hwpmc: Enable hwpmc support for AMD Family 17H devices
Adds new counters and events for family 17H devices. Adds libpmc support for family 17H devices.
Direct commit to 11 as this is supported by way of JSON counter descriptions on 12 & HEAD.

Revert r330897:
This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes.
Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes.

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 :-)

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.

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 ;-) Reviewed by: gnn MFC after:1 month Sponsored by: Netflix Inc.

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.

- Add support for PMCs in Intel CPUs of Family 6, model 0xE (Core Solo and Core Duo), models 0xF (Core2), model 0x17 (Core2Extreme) and model 0x1C (Atom).
In these CPUs, the actual numbers, kinds and widths of PMCs present need to queried at run time. Support for specific "architectural" events also needs to be queried at run time.
Model 0xE CPUs support programmable PMCs, subsequent CPUs additionally support "fixed-function" counters.
- Use event names that are close to vendor documentation, taking in account that: - events with identical semantics on two or more CPUs in this family can have differing names in vendor documentation, - identical vendor event names may map to differing events across CPUs, - each type of CPU supports a different subset of measurable events.
Fixed-function and programmable counters both use the same vendor names for events. The use of a class name prefix ("iaf-" or "iap-" respectively) permits these to be distinguished.
- In libpmc, refactor pmc_name_of_event() into a public interface and an internal helper function, for use by log handling code.
- Minor code tweaks: staticize a global, freshen a few comments.

Add convenience APIs pmc_width() and pmc_capabilities() to -lpmc. Have pmcstat(8) and pmccontrol(8) use these APIs.
Return PMC class-related constants (PMC widths and capabilities) with the OP GETCPUINFO call leaving OP PMCINFO to return only the dynamic information associated with a PMC (i.e., whether enabled, owner pid, reload count etc.).
Allow pmc_read() (i.e., OPS PMCRW) on active self-attached PMCs to get upto-date values from hardware since we can guarantee that the hardware is running the correct PMC at the time of the call.
Bug fixes: - (x86 class processors) Fix a bug that prevented an RDPMC instruction from being recognized as permitted till after the attached process had context switched out and back in again after a pmc_start() call.
Tighten the rules for using RDPMC class instructions: a GETMSR OP is now allowed only after an OP ATTACH has been done by the PMC's owner to itself. OP GETMSR is not allowed for PMCs that track descendants, for PMCs attached to processes other than their owner processes.
- (P4/HTT processors only) Fix a bug that caused the MI and MD layers to get out of sync. Add a new MD operation 'get_config()' as part of this fix.
- Allow multiple system-mode PMCs at the same row-index but on different CPUs to be allocated.
- Reject allocation of an administratively disabled PMC.
