 Trying to do a ASan build for #27531 results in build breakage due to
 `--enable-tests` and `--enable-debug`. In the first case we get
 {{{

 124fa904c4b2/mfbt/tests/TestWrappingOperations.cpp:27:1: error: non-
 constant condition for static assertion

 'mozilla::detail::WrapToSignedHelper<UnsignedType>::compute<unsigned
 char>(((int)aValue))'
 }}}
 and similar errors. Disabling tests results in packaging errors
 {{{
