Mehdi Amini 945a660cbc Change the fast-isel-abort option from bool to int to enable "levels"
Summary:
Currently fast-isel-abort will only abort for regular instructions,
and just warn for function calls, terminators, function arguments.
There is already fast-isel-abort-args but nothing for calls and
terminators.

This change turns the fast-isel-abort options into an integer option,
so that multiple levels of strictness can be defined.
This will help no being surprised when the "abort" option indeed does
not abort, and enables the possibility to write test that verifies
that no intrinsics are forgotten by fast-isel.

Reed Kotler 32be74b178 Add mips32 r1 to the list of supported targets for 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

Daniel Sanders 1f6f0f4b54 [mips] Use MTHC1 when it is available (MIPS32r2 and later) for both FP32 and FP64
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

Alp Toker 267d1f1cc9 Revert "Do materialize for floating point"
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:
start to do simple constants

add test case

format

Merge branch 'master' into 1756_8

Add basic functionality for assignment of ints. This creates a lot of core infrastructure in which to add, with little effort, quite a bit more to mips fast-isel
