existing libunwind used '0' in lsda_encoding as 'not present,'
whereas that is a valid encoding and does occur and would be
ignored. a missing encoding is actually 0xff.
The commit that addresses this is:
commit 8d4b51028d1a12b58d616f4b605254a877caafcf

0 is a valid LSDA encoding and can be seen in statically linked
programs. Initialize lsdaEncoding to DW_EH_PE_omit and check for that
value to decide whether a value should be decoded.
more bugfixes are necessary. this update is up to:

Lazy VFP processing works a lot better if the functions contain a return
instruction.
