Summary: Implement conversion of 64 to 32 bit floating point numbers (fptrunc) in mips fast-isel

Summary:
Expand list of supported targets for Mips to include mips32 r1.
Previously it only include r2. More patches are coming where there is
a difference but in the current patches as pushed upstream, r1 and r2
are equivalent.
Test Plan:
simplestorefp1.ll
add new build bots at mips to test this flavor at both -O0 and -O2

a base GOT entry.
Summary:
get tip of tree mips fast-isel to pass test-suite
Two bugs were fixed:
1) one bit booleans were treated as 1 bit signed integers and so the literal '1' could become sign extended.
2) mips uses got for pic but in certain cases, as with string constants for example, many items can be referenced from the same got entry and this case was not handled properly.

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.

Summary:
To make this work for both AFGR64 and FGR64 register sets, I've had to make the
instruction definition consistent with the white lie (that it reads the lower
32-bits of the register) when they are generated by expandBuildPairF64().
Corrected the definition of hasMips32r2() and hasMips64r2() to include
MIPS32r6 and MIPS64r6.
Depends on D3956

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.
