[C++ PATCH, committed] Fix libstdc++ regressions due to my access checking changes

[Kriang Lerdsuwanakij]

Hi

The access checking work I installed earlier still missed one function 
'synthesize_method'.  I overlooked this particular case, focusing on
only template instantiation codes.  We need to get out of deferring
check when we are synthesizing ctors/dtors as well.  I installed this
on the main trunk to fix a couple libstdc++ testsuite regressions
due to my earlier patches.

	* method.c (synthesize_method): Call push/pop_deferring_access_checks.
