    [testsuite, nvptx] Fix gcc.dg/tls/thr-cse-1.c
    
    With nvptx, we run into:
    ...
    FAIL: gcc.dg/tls/thr-cse-1.c scan-assembler-not \
      emutls_get_address.*emutls_get_address.*
    ...
    because the nvptx assembly looks like:
    ...
      call (%value_in), __emutls_get_address, (%out_arg1);
      ...
    // BEGIN GLOBAL FUNCTION DECL: __emutls_get_address
    .extern .func (.param.u64 %value_out) __emutls_get_address (.param.u64 %in_ar0);
    ...
    
    Fix this by checking the slim final dump instead, where we have just:
    ...
       12: r35:DI=call [`__emutls_get_address'] argc:0
    ...
    
    gcc/testsuite/ChangeLog:
    
    2020-09-24  Tom de Vries  <tdevries@suse.de>
    
            * gcc.dg/tls/thr-cse-1.c: Scan final dump instead of assembly for
            nvptx.
