Fix reordering of shuffles and binary operations

Do not apply transformation:

    BinOp(shuffle(v1), shuffle(v2)) -> shuffle(BinOp(v1, v2))

if operands v1 and v2 are of different size.
This change fixes PR19717, which was caused by r208488.

AVX-512: changes in intrinsics
1) Changed gather and scatter intrinsics. Now they are aligned with GCC built-ins. There is no more non-masked form. Masked intrinsic receives -1 if all lanes are executed.
2) I changed the function that works with intrinsics inside X86ISelLowering.cpp. I put all intrinsics in one table. I did it for INTRINSICS_W_CHAIN and plan to put all intrinsics from WO_CHAIN set to the same table in order to avoid the long-long "switch". (I wanted to use static map initialization that allowed by C++11 but I wasn't able to compile it on VS2012).
3) I added gather/scatter prefetch intrinsics.
4) I fixed MRMm encoding for masked instructions.

[ARM64] Add diagnostics for bitfield extract/insert instructions

Unfortunately, since ARM64 models all these instructions as aliases,
the checks need to be done at the time the alias is seen rather than
during instruction validation as AArch64 does it.

Fix type of shuffle obtained from reordering with binary operation

In transformation:
    BinOp(shuffle(v1,undef), shuffle(v2,undef)) -> shuffle(BinOp(v1, v2),undef)
type of the undef argument must be same as type of BinOp.

[mips] Replace FeatureFPIdx with FeatureMips4_32r2

Summary:
No functional change.

The minor change to the MIPS16 code is in preparation for a patch that will handle 32-bit FPIdx instructions separately to 64-bit (because they were added in different revisions)

[mips] Fold FeatureBitCount into FeatureMips32 and FeatureMips64

Summary:
DCL[ZO] are now correctly marked as being MIPS64 instructions. This has no
effect on the CodeGen tests since expansion of i64 prevented their use
anyway.

The check for MIPS16 to prevent the use of CLZ no longer prevents DCLZ as
well. This is not a functional change since DCLZ is still prohibited by
being a MIPS64 instruction (MIPS16 is only compatible with MIPS32).

No functional change

[mips] Marked up instructions added in MIPS-V and tested that IAS for -mcpu=mips[1234] does not accept them

Summary:
This required a new instruction group representing the 32-bit subset of
MIPS-V that was available in MIPS32R2

Most of these instructions are correctly rejected but with the wrong error
message. These have been placed in a separate test for now. It happens
because many of the MIPS V instructions have not been implemented.
