I don't think Vim remembers any place but the last where a mapping
was defined. However, you can start Vim like this,

$ vim -V15verbose.out ...

and capture all the ex commands to the file verbose.out. Then you
can open that file and search for

map\s\+,cs\>

or filter verbose.out with something like this

$ grep 'map[^I ][^I ]*,cs\>\|^[^l]' verbose.out | grep -C2 map

to find the various places where that mapping was defined. Those ^I
pairs are literal tabs. The "\|^[^l]" is there to capture all the
lines saying what file is being sourced, function being called,
etc., without all the lines beginning with "line " other than the
one(s) defining your mapping.

:verbose function CheckSyntax

will tell you where the function was last defined.
