Top-Down Microarchitecture Analysis (TMA) metrics simplify
cycle-accounting using microarchitecture-abstracted metrics
organized in one hierarchy. This update is from version 4.5 to
4.7.

The update includes:

 - tma_info_bottleneck* metrics, an abstraction or summarization of
   the 100+ TMA tree nodes into 12-entry familiar performance metrics.
 - Reduce number of events (multiplexing) for tma_info_system_gflops,
   tma_info_core_flopc, tma_info_inst_mix_ipflop and tma_ports_utilized_0.
 - Fixes for tma_info_bottleneck_mispredictions and
   tma_info_bad_spec_branch_misprediction_cost.
 - New tma_info_inst_mix_ippause metric.
 - tma_serializing_operation is raised to level 3.
 - Swapped tma_info_core_ilp (becomes per SMT thread) and
   tma_info_pipeline_execute (per physical core).
 - tma_nop_instructions and tma_shuffles_256b are lowered to level 4
   under tma_other_light_ops_group.
 - Reduced number of events when SMT is off.
 - Tuned thresholds for tma_info_bottleneck_branching_overhead,
   tma_fetch_bandwidth and tma_ports_utilized_3m.

If we instead decide to generate vmlinux.h from BTF info, it will be
there:

  $ pahole timespec64
  struct timespec64 {
  	time64_t                   tv_sec;               /*     0     8 */
  	long int                   tv_nsec;              /*     8     8 */

  	/* size: 16, cachelines: 1, members: 2 */
  	/* last cacheline: 16 bytes */
  };

  $

pahole manages to find it from /sys/kernel/btf/vmlinux, that is
generated from the kernel types.

With this linux/bpf.h doesn't need to be included, as its already in the
minimalistic tools/perf/util/bpf_skel/vmlinux/vmlinux.h file or what we
need comes when generating a vmlinux.h file from BTF info, i.e. when
using GEN_VMLINUX_H=1, as noticed by Namyung in a build break before
removing linux/bpf.h.

As a form of validation, it is a common practice to check the outputs
of commands whether they contain expected patterns or match a certain
regex.

Add helpers for verifying that all regexes are found in the output, that
all lines match any pattern from a set and that a certain expression is
not present in the output.

In verbose mode these helpers log mismatches for easier failure
investigation.

The test needs a struct machine and creates one for the current host,
but a side-effect is that struct machine has set up kernel maps
including module maps.

If the 'Symbols' test --dso option specifies a current kernel module,
it will already be present as a kernel dso, and a map with kmaps needs
to be used otherwise there will be a segfault - see below.

For that case, find the existing map and use that. In that case also,
the dso is split by section into multiple dsos, so test those dsos
also. That in turn, shows up that those dsos have not had overlapping
symbols removed, so the test fails.

Example:

  Before:

    $ perf test -F -v Symbols --dso /lib/modules/$(uname -r)/kernel/arch/x86/kvm/kvm-intel.ko
     70: Symbols                                                         :
    --- start ---
    Testing /lib/modules/6.7.2-local/kernel/arch/x86/kvm/kvm-intel.ko
    Segmentation fault (core dumped)

  After:

    $ perf test -F -v Symbols --dso /lib/modules/$(uname -r)/kernel/arch/x86/kvm/kvm-intel.ko
     70: Symbols                                                         :
    --- start ---
    Testing /lib/modules/6.7.2-local/kernel/arch/x86/kvm/kvm-intel.ko
    Overlapping symbols:
     41d30-41fbb l vmx_init
     41d30-41fbb g init_module
    ---- end ----
    Symbols: FAILED!

Every architecture can provide a register list for sampling. If an
architecture doesn't support register sampling, it won't define the data
structure 'sample_reg_masks'. Consequently, any code using this
structure must be protected by the macro 'HAVE_PERF_REGS_SUPPORT'.

This patch defines a weak function, arch__sample_reg_masks(), which will
be replaced by an architecture-defined function for returning the
architecture's register list. With this refactoring, the function always
exists, the condition checking for 'HAVE_PERF_REGS_SUPPORT' is not
needed anymore, so remove it.

Currently, the macro HAVE_PERF_REGS_SUPPORT is used as a switch to turn
on or turn off the code of perf registers. If any architecture cannot
support perf register, it disables the perf register parsing, for both
the native parsing and cross parsing for other architectures.

To support both the native parsing and cross parsing, the tool should
always build the perf regs functions. Thus, this patch removes
HAVE_PERF_REGS_SUPPORT from the perf regs files.

Counts were switched from the scaled saved value form to the
aggregated count to avoid double accounting. When this happened the
removing of scaling for a count should have been removed, however, it
wasn't and this wasn't observed as it normally doesn't matter because
a counter's scale is 1. A problem was observed with RAPL events that
are scaled.
