[PATCH 04/11] [analyzer] Add params to plugin.opt

[David Malcolm <dmalcolm at redhat dot com>]

Various commits on 2019-11-12 including r278083 through r278087
reimplemented parameter-handling in terms of options, so that
params are defined in params.opt rather than params.def.

This patch adds the params for the analyzer to plugin.opt,
replacing the patch:

  [PATCH 22/49] analyzer: params.def: new parameters
  https://gcc.gnu.org/ml/gcc-patches/2019-11/msg01520.html

from the original version of the patch kit.

gcc/ChangeLog:
	* analyzer/plugin.opt (-param=analyzer-bb-explosion-factor=): New
	param.
	(-param=analyzer-max-enodes-per-program-point=): New param.
	(-param=analyzer-max-recursion-depth=): New param.
	(-param=analyzer-min-snodes-for-call-summary=): New param.
