ARB_vertex_program and ARB_fragment_program define 0^0 = 1 (while GLSL
leaves it undefined). Performing fpow lowering in NIR would break this
behavior, preventing us from using prog_to_nir.
According to llvm/lib/Target/AMDGPU/SIInstructions.td, POW_common
expands to <V_LOG_F32_e32, V_EXP_F32_e32, V_MUL_LEGACY_F32_e32>,
which presumably does a zero-wins multiply.
Lowering in NIR results in a non-legacy multiply, where:
pow(0, 0) = 2^(log2(0) * 0)
= 2^(-INF * 0)
= 2^(-NaN)
= -NaN
which isn't the desired result.
This reverts:
- commit d6b7539206
(ac/nir: remove emission of nir_op_fpow)
- commit 22430224fe
(radeonsi/nir: enable lowering of fpow)
and prevents a regression in gl-1.0-spot-light with AMD_DEBUG=nir
after enabling prog_to_nir in st/mesa later in this series.

This removes some scalar loads from shaders, but it increases
the number of SET_SH_REG packets. This is currently basic but
it could be improved if needed. Inlining dynamic offsets might
also help.

the naming is a bit confusing no matter how you look at it. Within SPIR-V
"global" memory is memory accessible from all threads. glsl "global" memory
normally refers to shader thread private memory declared at global scope. As
we already use "shared" for memory shared across all thrads of a work group
the solution where everybody could be happy with is to rename "global" to
"private" and use "global" later for memory usually stored within system
accessible memory (be it VRAM or system RAM if keeping SVM in mind).
glsl "local" memory is memory only accessible within a function, while SPIR-V
"local" memory is memory accessible within the same workgroup.
v2: rename local to function as well
