During class file generation...
During class file generation, generate_classfile occasionally writes
out a bunch of data and then skips backwards to fill in blanks. When
configured with --enable-checking, this patching up will often trip
the checking code. This change introduces UNSAFE_PUTx macros which
never use CHECK_PUT. These should only be used in cases we know
CHECK_PUT will fail.
