Several test cases in g++.dg/debug/dwarf2 don't work when
-fdebug-types-section is enabled. In all but one case, the test cases
are fine and -fdebug-types-section works fine -- it's just that the
patterns in the assembly code don't match when the option is on.
I'm committing the following patch to force -fno-debug-types-section
for these cases so that they're independent of any change to the
default or an overriding option when running the test suite.

In the one remaining case -- pubnames-2.C -- I found a real bug in the
generation of the pubnames tables when -fdebug-types-section is
on, and I'll follow up with a fix for that.
