Alexey Budankov 2566349648 perf record: Enable LBR callstack capture jointly with thread stack 
Enable '-j stack' applicability together with '--call-graph dwarf'
option so thread stack data and LBR call stack could be captured
jointly:

  $ perf record -g --call-graph dwarf,1024 -j stack,u -- stack_test

Collected LBR call stack can be used to augment DWARF call stack
calculated from the raw thread stack data and to provide more
comprehensive call stack information for cases when collected SIZE is
not enough to cover complete thread stack.

Such cases are typical for workloads that allocate large arrays of data
on its threads stacks or the possible SIZE to collect can't be large
enough due to workload nature or system configuration and this is where
hardware captured LBR call stacks can provide missing stack frames.
Possible DWARF plus LBR call stacks consolidation algorithm description
follows.

With this patch set perf report command UI currently ignores collected
LBR call stack data and still provides DWARF based call stacks
information.

  Overview:

   Legend:

   THS - thread stack
   CTX - thread register context
   SWS - software stack
   SSF - skipped stack frames
   PSS - Perf sample stack

   ip,sp,bp - HW registers values
   d        - allocated stack regions
   kip      - ip address in the kernel space
   K        - captured thread stack size
