[analyzer] Overhaul how the static analyzer expects CFGs by forcing CFGs to be linearized only when used by the static analyzer.  This required a rewrite of LiveVariables, and exposed a ton of subtle bugs.

The motivation of this large change is to drastically simplify the logic in ExprEngine going forward.

Some fallout is that the output of some BugReporterVisitors is not as accurate as before; those will
need to be fixed over time.  There is also some possible performance regression as RemoveDeadBindings
will be called frequently; this can also be improved over time.

point, ASTReader::InitializeSema() has very little interesting work,
*except* issues stemming from preloaded declarations. That's something
we'll still need to cope with.

Refactor the */& mismatch fixit generation out of SemaOverload and provide a simple conversion checking function.

Switch the ModuleManager over to using a FileManager and FileEntry* as part of its lookup instead of the filename.  This is a more correct unique identifier, as symlinks can be handled by the FileManager.

that it accumulates referenced selectors from each of the modules/PCH

we could turn this into an on-disk hash table so we don't load the
whole thing the first time we need it. However, it tends to be very,
very small (i.e., empty) for most precompiled headers, so it isn't all
that interesting.

__block variables where the act of initialization/assignment
itself causes the __block variable to be copied to the heap
because the variable is of block type and is being assigned
a block literal which captures the variable.

For PCH files, have only one open/close for temporary + rename to be safe from race conditions.
For all other output files open/close the output file directly.

use in KEXTs. However, users/Xcode still need to tweak the linker flags to do 
the right thing, and end up using -Xlinker, for example.  Instead, have the 
driver "do the right thing" when linking when -fapple-kext is present on the 
command line, and we should have Xcode use -fapple-kext instead of setting other
flags like -Xlinker -kext or -nodefaultlibs.

  - Added LazyVector::erase() to support this use case.
  - Factored out the LazyDecl-of-Decls to RecordData translation in
  the ASTWriter. There is still a pile of code duplication here to
  eliminate.

Add a utility function to the Lexer, which makes it easier to find a token after the given location. (It is a generalized version of trans::findLocationAfterSemi from ArcMigrate, which will be changed to use the Lexer utility).

contents are lazily loaded on demand from an external source (e.g., an
ExternalASTSource or ExternalSemaSource). The "loaded" entities are
kept separate from the "local" entities, so that the two can grow
independently.

Switch Sema::TentativeDefinitions from a normal vector that is eagerly
populated by the ASTReader into one of these LazyVectors, making the
ASTReader a bit more like me (i.e., lazy).
