ENH: add support for nan-like null strings in string replace #3476

Workflow file for this run

.github/workflows/linux_simd.yml at 0905dd8

	name: Linux SIMD tests

	# This file is meant for testing different SIMD-related build options and
	# optimization levels. See `meson_options.txt` for the available build options.
	#
	# Jobs and their purposes:
	#
	# - baseline_only:
	# Focuses on completing as quickly as possible and acts as a filter for other, more resource-intensive jobs.
	# Utilizes only the default baseline targets (e.g., SSE3 on X86_64) without enabling any runtime dispatched features.
	#
	# - old_gcc:
	# Tests the oldest supported GCC version with default CPU/baseline/dispatch settings.
	#
	# - without_optimizations:
	# Completely disables all SIMD optimizations and other compiler optimizations such as loop unrolling.
	#
	# - native:
	# Tests against the host CPU features set as the baseline without enabling any runtime dispatched features.
	# Intended to assess the entire NumPy codebase against host flags, even for code sections lacking handwritten SIMD intrincis.
	#
	# - without_avx512/avx2/fma3:
	# Uses runtime SIMD dispatching but disables AVX2, FMA3, and AVX512.
	# Intended to evaluate 128-bit SIMD extensions without FMA support.
	#
	# - without_avx512:
	# Uses runtime SIMD dispatching but disables AVX512.
	# Intended to evaluate 128-bit/256-bit SIMD extensions.
	#
	# - intel_sde:
	# Executes only the SIMD tests for various AVX512 SIMD extensions under the Intel Software Development Emulator (SDE).
