profile mode fix

     Here is the patch that simply consider 55083 as not supported 
except in normal mode. This is a temporary workaround for 4.9 release so 
I prefer not to introduce a dg-profile-mode-unsupported or something 
like that. Those tests will simply appear as not supported for debug and 
parallel mode even if they are, not a big deal, no ?

Tested under Linux x86_64 normal and profile mode.

     dg-require-normal-mode because not supported in profile mode.
     * testsuite/23_containers/unordered_set/ Likewise.

Ok to commit ?
