Revise the design of the Path concept per peer review. Too many changes to
...
note individually but these essence of it is to not derive from
std::string, clarify the interface, and provide better documentation.
There is now also (untested) implementations for AIX, Darwin, and SunOS.

Do not use .xword and friends to emit zeros on V9. Apparently there are issues
...
with emitting .xwords when not on an 8-byte boundary (.xword 0 is not the
same as 8 .byte 0's). Because we do not know when or when we are not aligned,
just emit bytes like the old V9 asmprinter did.

Bytecode Analyzer Cleanup:
...
- Rearrange output order to make more sense
- Make only the function level output count as "detailed"
- Output dump output directly to stream, don't buffer it.
- Fix counting of block sizes
- Implement new handlers for number of types, dependent libs, target triple
- Compute the size of block headers.

Bytecode Reader Cleanup:
...
- provide the correct conversion for ModuleBlockID in read_block (a potential
bug but not actually exploited because reading module block ids doesn't
use read_block).
- install support for handleTypeList handler
- install support for handleDependentLibrary handler
- install support for handleTargetTriple handler
- clean up comments, output strings,
- ensure that processing function arguments doesn't SIGSEGV if one of the
arguments is a null pointer (yeah, it happened .. weird)
- prepare for version 5 bytecode by documenting what will change.
