bug#30491: 26.0; (elisp) `Profiling'

[Drew Adams]

1. "how much resource" is not good English.  How much of a given
   resource or how many resources, not how much resource.  "Resource" is
   a countable noun.

2. "See the functions 'benchmark-run' and 'benchmark-run-compiled'".
   Those are macros, not functions.  And it should probably mention
   command `benchmark'.

3. The node should say something about library `elp', or it should not
   mention it.  The approach should be similar to what is said about
   library `benchmark.el', at a minimum.

4. A simple example of using the profiler commands would be welcome.
