[PATCH][pushed] opts: Sanity check for param names.

[Martin Liška]

Hello.

This provides new sanity check:
options.c:1:2: error: #error Parameter option name 
'-param-ipa-jump-function-lookups=' must start with '-param='
    1 | #error Parameter option name '-param-ipa-jump-function-lookups=' must 
start with '-param='
      |  ^~~~~

Apart form that, I fix the affected option.
I'm going to install the patch.
Martin

gcc/ChangeLog:

        * optc-gen.awk: Check that params start with -param=.
        * params.opt: Fix ipa-jump-function-lookups.
