performance.

An MBB which branches to an EH landing pad shouldn't be considered for tail merging.

In SjLj EH, the jump to the landing pad is not done explicitly through a branch
statement. The EH landing pad is added as a successor to the throwing
BB. Because of that however, the branch folding pass could mistakenly think that
it could merge the throwing BB with another BB. This isn't safe to do.

linked against a debug LLVM, runs a variety of
functions -- currently just one -- that verify
that the Decls we create are valid.

ClangASTContext now calls this verifier whenever
it adds a Decl to a DeclContext, and the verifier
checks that the AccessSpecifier is sane.

lldb_private::Error objects the rules are:
- short strings that don't start with a capitol letter unless the name is a
  class or anything else that is always capitolized
- no trailing newline character
- should be one line if possible

Implemented a first pass at adding "--gdb-format" support to anything that
accepts format with optional size/count.

Add support for the notion of "hidden" relocations.  On MachO, these are relocation entries that are used as additional information for other, real relocations, rather than being relocations themselves.
I'm not familiar enough with ELF or COFF to know if they should have any relocations marked hidden.

Remove dead members/parameters: ProgramState, respondsToCallback, autoTransition.
Remove addTransition method since it's the same as generateNode. Maybe we should
rename generateNode to genTransition (since a transition is always automatically
generated)?
