panfrost: Implement Midgard shader toolchain 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.

panfrost/midgard: Lower source modifiers for ints 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.* Signed-off-by: Alyssa Rosenzweig <alyssa@rosenzweig.io>
