Add missing CFLAGS to instrument things for fuzzers. (#35082)

bzbarsky-apple · web-flow · commit fd9dfe26964b · 2024-08-21T17:03:39.000Z
-fno-sanitize-coverage=pc-table is added since we are already using
inline-8bit-counters and trace-cmp to provide instrumentation for the
fuzzers. It also helps reduce memory usage and improve fuzzer performance.
