[PATCH][OBVIOUS] Remove FIELD_DECL leftover.

[Martin Liška]

Hi.

The patch installed as r277614 is not exactly 1:1 to the previous
revision, but I forgot to remove hashing of FIELD_DECL. The tree type
is not handled in operand_equal_p.

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

I'm going to install it as obvious.
Thanks,
Martin
