[patch, mips] Fix for mips64 ieee754.h header file

[patch, mips] Fix for mips64 ieee754.h header file

[Steve Ellcey]

This patch is to ensure a consistent set of headers across various mips
platforms.  Currently mips32 platforms use ieee754.h from the sysdeps/mips
directory but mips64 targets use ieee754.h from sysdeps/ieee754/ldbl-128.
The one from sysdeps/mips can handle 64 bit or 128 bit long doubles and
the one from sysdeps/ieee754/ldbl-128 only handles 128 bit long doubles.

This change causes mips32 and mips64 targets to use the one from sysdeps/mips.
To make sure I don't mess up any other header files I moved ieee754.h
from the mips directory to mips/ieee754 so I could put it at the head of the
Implies list and not affect anything else.  I then changed Implies for mips32
(so that it doesn't change behaviour) and for mips64 so that it does change
behaviour and uses the mips specific ieee754.h file.

Tested on mips32, mips32r2, mips64, and mips64r2 builds with the o32, n32,
and 64 bit ABIs.

OK to checkin?

OK, but fix the ChangeLog entry (it goes in ports/ChangeLog.mips and the 
paths in that file are relative to that directory, so do not have the 
initial ports/ component).
