[PATCH][gold] Mips: Fix TLS LDM GOT entry

[Vladimir Radosavljevic <Vladimir dot Radosavljevic at imgtec dot com>]

For some cases TLS LDM entry was not added to the GOT. This patch fixes that.
It also shifts addend to reduce possibility of collisions (IIRC this was missed
from the original commit).

Regards,
Vladimir

ChangeLog -

	* mips.cc (Mips_got_entry::hash()): Shift addend to reduce
	possibility of collisions.
	(Mips_got_entry::equals): Fix case for GOT_TLS_LDM
	entries.
