In preparation for a Panfrost-based non-Gallium driver (maybe
Vulkan...?), hoist everything except for the Gallium driver into a
shared src/panfrost. Practically, that means the compilers, the headers,
and pandecode.

On Midgard, float ops support standard source modifiers (abs/neg) and
destination modifiers (sat/pos/round). Integer ops do not support these,
however. To cope, we use native NIR source modifiers for floats, but
lower them away to iabs/ineg for integers, implementing those ops
simultaneously to avoid regressions.
Fixes the integer tests in
dEQP-GLES2.functional.shaders.operator.unary_operator.minus.*

This patch implements the free Midgard shader toolchain: the assembler,
the disassembler, and the NIR-based compiler. The assembler is a
standalone inaccessible Python script for reference purposes. The
disassembler and the compiler are implemented in C, accessible via the
standalone `midgard_compiler` binary. Later patches will use these
interfaces from the driver for online compilation.
