f7b4fa2e24 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.

eb7256be64 Only update LiveVariables if it is available. addIntervalsForSpills
runs after the initial run of the live interval analysis.

7c06c0aeee 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...

6f0fa9867f 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.

05d5a44c02 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.

d7d70bdccb 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.

84d4e1b105 Two Changes:
- Pass the output stream to the analyzer so it can write its output there
  directly instead of buffering it.
- Don't pass a boolean to ParseBytecode because its not needed any more.

c0868628e0 Add boolean file format flags in preparation for version 5 bytecode.
Remove the "processFunctions" boolean from ParseBytecode as it is no
longer needed. This is part of avoiding double reading of functions

09976167c1 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.

e6aace2ecb Back out branchless SetCC code. While it helped a lot in some cases, it
hurt a lot in others.  Instead, improve branching version of SetCC and
Select instructions.  The old code will be in CVS should we ever need to
dig it up again.
