The INSTR_PROF_RAW_MAGIC_* number in profraw files should match during
profile merging. This causes an error with 32-bit and 64-bit variants
of the same code. The module signatures for the two binaries are
identical but they use different INSTR_PROF_RAW_MAGIC_* causing a
failure when profile-merging is used. Including it when computing the
module signature yields different signatures for the 32-bit and 64-bit
profiles.
