It wasn't obvious why it's there and what its role is.
Also, increase the "entertainment level" a bit.
I checked in STG and Cmm dumps that this really generates closures (and
is not e.g. constant folded away.)

The -fno-info-table-map-with-stack flag omits STACK info tables from the info
table map, and the -fno-info-table-map-with-fallback flag omits info tables
with defaulted source locations from the map. In a test on the Agda codebase
the build results were about 7% smaller when both of those types of tables
were omitted.
Adds a test that verifies that passing each combination of these flags
results in the correct output for -dipe-stats, which is disabled for the js
backend since profiling is not implemented.
This commit also refactors a lot of the logic around extracting info tables
from the Cmm results and building the info table map.
This commit also fixes some issues in the users guide rst source to fix
warnings that were noticed while debugging the documentation for these flags.
Fixes #23702
