- Output format and some of the code stolen from macho-dump.
- Somewhat incomplete and probably buggy.
- Comes with a very basic test.

Another beating by boost in this test case: http://llvm.org/PR8117
A function specialization wasn't properly initialized if it wasn't canonical.
I wish there was a nice little test case but this was boost.

this fixes all analyser test failures in my gcc34-based
environment
how the cast result could bind to the non-const ref is
somewhat mysterious and remains to be investigated; to
avoid similar miscompilations (by gcc34 only?)

The end result is now we eagarly constant-fold symbols in the analyzer that are perfectly constrained
to be a constant value. This allows us to recover some path-sensitivity in some cases by lowering
the required level of reasoning power needed to evaluate some expressions.
The net win from this change is that the false positive in PR 8015 is fixed, and we also
find more idempotent operations bugs.
We do, however, regress with the BugReporterVisitors, which need to be modified to understand
this constant folding (and look past it). This causes some diagnostic regressions in plist-output.m
which will get addressed in a future patch. plist-output.m is now marked XFAIL, while
plist-output-alternate.m now tests that the plist output is working, but with the suboptimal
diagnostics. This second test file will eventually be removed.

Renamed the "dispatchqaddr" setting that was coming back for stop reply packets
to be named "qaddr" so that gdb doesn't thing it is a register number. gdb
was checking the first character and assuming "di" was a hex register number
because 'd' is a hex digit. It has been shortened so gdb can safely ignore it.

Make get/set variable at the debugger level always set the particular debugger's instance variables rather than
the default variables.

the function processing the format string can decided whether or not to accept a null format string (e.g., asl_log). Fixes <rdar://problem/8269537>.

- Created private class CFGReachabilityAnalysis, which provides cached reachability lookups in the CFG
- Simplified PathWasCompletelyAnalyzed to use the new reachability class
- Added getLastRelevantNodes function for future use with path displaying in BugReporter

operand from the pseudo instruction to the new instruction as an implicit use.
This will preserve any other flags (e.g., kill) on the operand.

For VLD3/VLD4 with double-spaced registers, add the implicit use of the
super register for both the instruction loading the even registers and the
instruction loading the odd registers.

to selectively walk successors/predecessors based on commonly used filters. For starters, add
a filter to ignore 'default:' cases for SwitchStmts when all enum values are covered by CaseStmts.

covered by individual case statements. Flow-based analyses may wish to consult this information,
and recording this in the AST allows us to obviate reconstructing this information later when
we build the CFG.

TreeTransform, since we were getting an empty source range where we
shouldn't. Sadly, the test case is Boost.Proto, and isn't worth
reducing.
