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.

ca5d1c378c Now that LiveIntervals::addIntervalsForSpills is fixed, do not require
LiveVariables.

d8d26b3268 Only update LiveVariables if it is available. addIntervalsForSpills
runs after the initial run of the live interval analysis.

ccdf21af1f Back out this change as it broke the build last night. This should be
investicated further as the linearscan variants don't really need
LiveVariables...

07ea1917d0 Add the CompactionTableIsEmpty function so that we can determine if a
CompactionTable really needs to be emitted. This is not a straight forward
computation, hence the need for a member function here.

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:
- 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.
