Petar Jovanovic 9b8b9e81dd [mips][msa] Range adjustment for ldi_b builtin function operand 
Reasoning behind this change was allowing the function to accept all values
from range [-128, 255] since all of them can be encoded in an 8bit wide
value.
This differs from the prior state where only range [-128, 127] was accepted,
where values were assumed to be signed, whereas now the actual
interpretation of the immediate is deferred to the consumer as required.

Petar Jovanovic bc97ab28a4 [mips][msa] Remove range checks for non-immediate sld.[bhwd] instructions 
Removes immediate range checks for these instructions, since they have GPR
rt as their input operand.

Simon Dardis 1f90f2d33f [mips][msa] Range check MSA intrinsics with immediates 
This patch teaches clang to range check immediates for MIPS MSA instrinsics.
This checking is done strictly in comparison to some existing GCC
implementations. E.g. msa_andvi_b(var, 257) does not result in andvi $wX, 1.
Similarily msa_ldi_b takes a range of -128 to 127.

As part of this effort, correct the existing MSA test as it has both illegal
types and immediates.

Simon Dardis 3d9c763816 [mips] MSA intrinsics header file 
This patch adds the msa.h header file containing the shorter names for the
MSA instrinsics, e.g. msa_sll_b for builtin_msa_sll_b.

Daniel Sanders d5f554f0bb [mips][msa] Correct definition of bins[lr] and CHECK-DAG-ize related tests

Daniel Sanders ab94b537d7 [mips][msa] Added support for matching bmnz, bmnzi, bmz, and bmzi from normal IR (i.e. not intrinsics) 
Also corrected the definition of the intrinsics for these instructions (the
result register is also the first operand), and added intrinsics for bsel and
bseli to clang (they already existed in the backend).

These four operations are mostly equivalent to bsel, and bseli (the difference
is which operand is tied to the result). As a result some of the tests changed
as described below.

bitwise.ll:
- bsel.v test adapted so that the mask is unknown at compile-time. This stops
  it emitting bmnzi.b instead of the intended bsel.v.
- The bseli.b test now tests the right thing. Namely the case when one of the
  values is an uimm8, rather than when the condition is a uimm8 (which is
  covered by bmnzi.b)

compare.ll:
- bsel.v tests now (correctly) emits bmnz.v instead of bsel.v because this
  is the same operation (see MSA.txt).

i8.ll
- CHECK-DAG-ized test.
- bmzi.b test now (correctly) emits equivalent bmnzi.b with swapped operands
  because this is the same operation (see MSA.txt).
- bseli.b still emits bseli.b though because the immediate makes it
  distinguishable from bmnzi.b.

vec.ll:
- CHECK-DAG-ized test.
- bmz.v tests now (correctly) emits bmnz.v with swapped operands (see
  MSA.txt).
- bsel.v tests now (correctly) emits bmnz.v with swapped operands (see
  MSA.txt).

Daniel Sanders d74b130cc9 [mips][msa] Added support for matching bins[lr]i.[bhwd] from normal IR (i.e. not intrinsics) 
This required correcting the definition of the bins[lr]i intrinsics because
the result is also the first operand.

It also required removing the (arbitrary) check for 32-bit immediates in
MipsSEDAGToDAGISel::selectVSplat().

Currently using binsli.d with 2 bits set in the mask doesn't select binsli.d
because the constant is legalized into a ConstantPool. Similar things can
happen with binsri.d with more than 10 bits set in the mask. The resulting
code when this happens is correct but not optimal.

Daniel Sanders ffd8df29b6 [mips][msa] Add intrinsics that map to pseudo-instructions. 
Unlike the previously added intrinsics, these do not map to a single instruction
on MIPS32. They are provided for regularity (to round out the .[bhw] variants
of the same operation) and compatibility with GCC.

Includes:
  copy_[us].d, fill.d, insert.d, insve.d
