[PATCH 0/2] wmd speedup

[Eric Pouech]

The following series drastically improves cmd performance by caching
label resolution when executing a batch file.

Testbot is hitting a timeout when running the tests.
See https://bugs.winehq.org/show_bug.cgi?id=52720

Local tests show a reduction of test duration of 90%!
Don't always expect those numbers; in some extreme cases, the patchset
will even slightly increase execution time.

Note: the reason why testbot started timing out is still unknown.
