1605d22f77 Give the -time-passes tool option a global storage location so that its

66d61f3a72 Fix a bug in a previous checkin of mine, correcting 
Regression.CodeGen.Generic.2004-04-09-SameValueCoalescing.llx and the
code size problem.

This bug prevented us from doing most register coallesces.

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:

  directly instead of buffering it.

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.

error message, print out:

b9ab0ef60d Fix PR422. 
Ouch! Changes in the lazy initialization code caused each incorporated
function to reprocess the entire function on every lookup of a value's
slot number. This caused a horrible slowdown in all functions. This
fix made llvm-dis go from "longer than I care to wait" (minutes) on a large
test case to 0.53 seconds.

to use R31 (our FP) in functions that have a frame pointer.  These changes

absolute position on the command line. Similarly allow any cl::list to
use the method getPosition(n) to retrieve the absolute position of the nth
option in the list. This provides support for two things: (a) options like
-l that are actually positional and their order of occurrence matters when
they are intermixed with positional arguments like "a.o"; and (b) options
like -x LANG which affect only the positional arguments that come after
the option. In both cases, knowing the absolute position of a given option
helps.
