[PATCH] TARGET_<xxx> support, was [PATCH] Rs6000 infrastructure cleanup

[Michael Meissner <meissner at linux dot vnet dot ibm dot com>]

The powerpc port is running out of switches that set bits in target_flags, and
I am in the process of changing all of the switches to use a secondary flag
word that is HOST_WIDE_INT (at least 64-bits on powerpc).  One of the changes
is that the options machinery changes all of the TARGET_<xxx> names to
OPTION_<xxx>.  Joseph and I have been talking about going back to using
TARGET_<xxx> all of the time.

I did some digging, and there are only two ports that use this:
  1) The x86 had a similar problem some time ago; (and)
  2) All Android linux ports uses it for setting a single bit to avoid adding
     any bits to the target_flags in the target machine.

I made a set of changes to make this change.  I have bootstrapped the x86
compiler with no problems, and before I go home tonight, I will kick off a
build/make compare of an unmodified tree.  Assuming there are no regressions
found, are these patches ok to check in?

Now, the x86 actually maps the OPTION_ISA_xxx switches to TARGET_xxx switches,
so it is easy to change all of the defines from OPTION_ISA_<xxx> to
TARGET_ISA_<xxx>.  For Android, it was simple to change the one line of
reference.
