passes in the mips back end. This, unfortunately, required a
bit of churn in the various predicates to use a pointer rather
than a reference.

Summary:
This patches allows non conversions like i1=i2; where both are global ints.
In addition, arithmetic and other things start to work since fast-isel will use
existing patterns for non fast-isel from tablegen files where applicable.
In addition i8, i16 will work in this limited context for assignment without the need
for sign extension (zero or signed). It does not matter how i8 or i16 are loaded (zero or sign extended)
since only the 8 or 16 relevant bits are used and clang will ask for sign extension before using them in
arithmetic. This is all made more complete in forthcoming patches.
for example:
int i, j=1, k=3;
void foo() {
i = j + k;
}
Keep in mind that this pass is not enabled right now and is an experimental pass
It can only be enabled with a hidden option to llvm of -mips-fast-isel.
Test Plan: Run test-suite, loadstore2.ll and I will run some executable tests.

1) The commit was made despite profound lack of understanding:
"I did not understand the comment about using dyn_cast instead of isa. I will
commit as is and make the update after. You can explain what you meant to me."
Commit first, understand later isn't OK.
2) Review comments were simply ignored:
"Can you edit the summary to describe what the patch is for? It appears to be
a list of commits at the moment."
3) The patch got LGTM'd off-list without any indication of readiness.
4) The public mailing list was excluded from patch review so all of this was
hidden from the community.
This reverts commit r210414.

Summary: Merge branch 'master' into 1758_6
Test Plan:
No functionality change. Run "make check" and run test-suite.
Because our servers are not yet running again I have not yet run test-suite.
I will further review myself before submission.

Summary:
Included this file which is needed to enable tablegen generated functionality
for fast mips-isel
Test Plan:
This has no visible functionality by itself but just adding the include
file creates some issues so I have it as a separate patch.
