Both now list their routines (GetFixedCodeLabels), so the disassembly
names jump targets and --jit-profile charges routine samples to the
calling block. The profiler samples them on Linux, and its report
disassembles their host code per instruction (RISC-V's in 2- and 4-byte
steps).

The native IR JITs get the emulator thread's host PC sampled every 50 us (a
signal on macOS and Linux, SuspendThread on Windows), mapped to blocks, the
routines they call and host functions. The report has each hot block's MIPS,
IR and host code with the samples per host instruction. The IR interpreter's
block timing, previously behind IR_PROFILING, now runs on the same switch.
Both cost nothing when off.
