f2f0781a10 Implement the following missing functionality in the PPC backend:
cast fp->bool
cast ulong->fp
algebraic right shift long by non-constant value
These changes tested across most of the test suite.  Fixes Regression/casts

8e66595512 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.

7af2865fc6 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.

911ec6d1c0 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.

5b472d9879 Bytecode Reader Cleanup:

- 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.
