[PATCH] Fix PR 51198, DECL_INITIAL still contains stuff for FIELD_DECLs

Subject: [PATCH] Fix PR 51198, DECL_INITIAL still contains stuff for FIELD_DECLs

Hi,
  With C++11's decl initialization for non static members, the
DECL_INITIAL for FIELD_DECLs contains stuff which we don't need to
keep around after the front-end is done.  This patch clears them in
the free_lang_data pass.

OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.

Thanks,
Andrew Pinski

ChangeLog:
* tree.c (free_lang_data_in_decl): Clear FIELD_DECL's DECL_INITIAL also.

testsuite/ChangeLog:
* g++.dg/torture/pr51198.C: New testcase.
