[PATCH 0/5] Change some index-cache commands

[Simon Marchi]

Reviewing Aaron's debuginfod series (which adds a command to
enable/disable the use of debuginfod) made me reconsider how I
designed the index-cache commands.  The details about that are in the
last two patches.  The first three patches are preparatory cleanups or
improvements.

Simon Marchi (5):
  gdb: pass/return setting setter/getter scalar values by value
  gdb: remove unnecessary cmd_list_element::aliases nullptr checks
  gdb: remove command_class enum class_deprecated
  gdb: add "info index-cache stats", deprecate "show index-cache stats"
  gdb: introduce "set index-cache enabled", deprecate "set index-cache
    on/off"
