We can bundle two load/store together. This eliminates the need for
explicit load/store pairing in a prepass, as well.

Conditions for branches don't have a swizzle explicitly in the emitted
binary, but they do implicitly get swizzled in whatever instruction
wrote r31, so we need to handle that.
Signed-off-by: Alyssa Rosenzweig <alyssa.rosenzweig@collabora.com>
Conditional instructions (csel and conditional branches) require their
condition to be written to a special condition pipeline register (r31.w
for scalar, r31.xyzw for vector). However, pipeline registers are live
only for the duration of a single bundle. As such, the logic to schedule
conditionals correct is surprisingly complex. Essentially, we see if we
could stuff the conditional within the same bundle as the csel/branch
without breaking anything; if we can, we do that. If we can't, we add a
dummy move to make room.

A bit of a kludge but allows setting an implicit dependency of synthetic
conditional moves on the actual condition, fixing code generated like:
vmul.feq r0, ..
sadd.imov r31, .., r0
vadd.fcsel [...]
The imov runs simultaneous with feq so it gets garbage results, but it's
too late to add an actual dependency practically speaking, since the new
synthetic imov doesn't have a node associated.

In the future, we will want to keep track of which components of
constants of various sizes correspond to which parts of the bundle
constants, like in the old scheduler. For now, let's just stub it out
for a simple rule of one instruction with embedded constants per bundle.
We can eventually do better, of course.

After we've chosen an instruction, popped it off, and processed it, it's
time to update the worklist, removing that instruction from the
dependency graph to allow its dependents to be put onto the worklist.
Signed-off-by: Alyssa Rosenzweig <alyssa.rosenzweig@collabora.com>
In the future, this routine will implement the core scheduling logic to
decide which instruction out of the worklist will be scheduled next, in
a way that minimizes cycle count and register pressure.
In the present, we are more interested in replicating in-order
scheduling with the much-more-powerful out-of-order model. So rather
than discriminating by a register pressure estimate, we simply choose
the latest possible instruction in the worklist.

There are some optimizations which are only implemented for additions
and some optimizations which assume that subtractions have been lowered.
By lowering all subtractions first and later recombine for backends
which prefer this option, we don't have to implement them twice.
This patch also moves lower_negate to nir_opt_algebraic_late() to enable
these optimizations for backends which make use of it.

This patch is based on 28e3f85e09/mingw-w64-mesa/link-ole32.patch but with tweaks to avoid MSVC build break when applied.
v2: Create Mingw platform alias pointing to windows host platform define to avoid spurious crosscompilation;
v3: Fix obviously wrong compiler flags for swr driver;
v4: Update original patch URL because it has been relocated;
v5: Don't bother patching autools stuff as it's not used by MSYS2 Mingw-w64 build and it's days are numbered anyway;
v6: After Mingw posix flag fix in 295851eb things are far simpler as we don't need more linking of uuid, ole32, version and shell32 than what is already in place.
As X86AsmPrinter component is gone, LLVMX86AsmPrinter got replaced
with LLVMRemarks, LLVMBitstreamReader and LLVMDebugInfoDWARF.
Tests done with llvm-config on both LLVM 8 and 9 indicate that
mcjit, bitwriter and x86asmprinter fully fit inside engine component.
On other platforms and with meson build mcdisassembler was used to replace
X86AsmPrinter but mcdisassembler also fully fits inside engine component
for LLVM>=8 according to same tests.
v2: Avoid duplicating code related to Mingw pthreads.

The PP uniforms address register in render state is not a direct pointer
to the uniforms storage -- instead, it points to an one-item array, and
the array item is the real pointer to the uniforms storage.
This register reuses some of its LSBs as a size field. Currently the
size is set according to the length of the real uniforms storage.
However, as the register itself contains only a pointer to the one-item
array, the size field should be set to the length of the one-item array
and subtract it by 1, which means a fixed value of 0. That means we can
just omit it now.
Test shows this should be the correct approach to set this register.

glsl 4.4 spec section '5.9 expressions':
"The operator is multiply (*), where both operands are matrices or one operand is a vector and the
other a matrix. A right vector operand is treated as a column vector and a left vector operand as a
row vector. In all these cases, it is required that the number of columns of the left operand is equal
to the number of rows of the right operand. Then, the multiply (*) operation does a linear
algebraic multiply, yielding an object that has the same number of rows as the left operand and the
same number of columns as the right operand. Section 5.10 “Vector and Matrix Operations”
explains in more detail how vectors and matrices are operated on."
This fix disallows a multiplication of incompatible matrices like:
mat4x3(..) * mat4x3(..)
mat4x2(..) * mat4x2(..)
mat3x2(..) * mat3x2(..)
