One way to exit the loop is through an unwind edge. However, that may involve
splitting the critical edge of the landing pad, which is non-trivial. Prevent
the transformation from rewriting the landing pad exit loop block.

all AST files have a normal METADATA record that has the same form
regardless of whether we refer to a chained PCH or any other kind of
AST file.

Introduce the IMPORTS record, which describes all of the AST files
that are imported by this AST file, and how (as a module, a PCH file,
etc.). Currently, we emit at most one entry to this record, to support
chained PCH.

Plus, isSynthesized returning true does not mean that there is not a user-declared method declaration.

Things are much saner now. We no longer need to modify the laning pads, because
of the invariants we impose upon them. The only thing DwarfEHPrepare needs to do
is convert the 'resume' instruction into a call to '_Unwind_Resume'.

Revert r137781; I agree with Duncan's comment that the situation in question is clearly impossible given the current structure of the code.

New category "gnu-libstdc++" provides summary for std::string and synthetic children for types std::map, std::list and std::vector
 The category is enabled by default. If you run into issues with it, disable it and the previous behavior of LLDB is restored
 ** This is a temporary solution. The general solution to having formatters pulled in at startup should involve going through the Platform.
Fixed an issue in type synthetic list where a category with synthetic providers in it was not shown if all the providers were regex-based

with unknown instructions.

Allow the MCDisassembler to return a "soft fail" status code, indicating an instruction that is disassemblable, but invalid.  Only used for ARM UNPREDICTABLE instructions at the moment.
