In test_intel_pt.sh, the test script compiled two external C programs at
runtime using /usr/bin/cc (a thread loop workload and a JIT self-
modifying workload). Relying on external C compilers inside shell tests
frequently causes failures in continuous integration environments.
Create a built-in 'jitdump' workload and switch test_intel_pt.sh to use
'perf test -w thloop' and 'perf test -w jitdump'. Also add multi-
architecture compatibility without external C compiler dependencies, the
workload instruction arrays dynamically encode CHK_BYTE into opcodes
across x86, ARM32, ARM64, RISC-V, PowerPC, MIPS, LoongArch, and s390x.
Some minor include fixes for util/jitdump.h.
