This adds a simple code profiler that leverages both SysTick and the Performance Monitoring Unit (PMU) available on Armv8.1-M cores. SysTick provides a simple high-resolution timer source, while the PMU offers a cycle counter and multiple configurable event counters that can track low-level performance metrics such as cache misses, pipeline stalls, etc... See the Armv8.1-M Performance Monitoring User Guide for additional details. Function-level instrumentation is enabled using -finstrument-functions on select files to automatically record statistics on entry/exit. Signed-off-by: iabdalkader <i.abdalkader@gmail.com>
