Some tests are explicitly testing -var-create e.g mi-var-cmd.exp, others
might not be but still provide a handy check on the output e.g

*** gdb.mi/mi-var-child.exp
  
  # Test: c_variable-4.2
  # Desc: create variable "struct_declarations"
  mi_gdb_test "-var-create struct_declarations * struct_declarations" \
  	"\\^done,name=\"struct_declarations\",numchild=\"11\",type=\"struct _struct_decl\"" \
 	"create local variable struct_declarations"

I don't really like mi_create_varobj as it removes checks on type, number of
children etc.  How about if I revert all my changes which use mi_create_varobj
and just add value=\".*\" to the regexp in each mi_gdb_test for -var-create?
