[Qemu-devel] [PATCH v3 3/9] tests/tcg: target/mips: Add a header with test utilities

[Aleksandar Markovic <aleksandar.markovic@rt-rk.com>]

From: Aleksandar Markovic <amarkovic@wavecomp.com>

Add a header that contains test utilities. For now, it contains
only a function for checking and printing test results for bit
counting and similar MSA instructions.
