Sean Callanan dc00334dc3 Added support to the expression parser for finding
Objective-C types and enums in modules.  We now have
a three-stage fallback when looking for methods and
properties: first the DWARF, second the modules, third
the runtime.

Duncan P. N. Exon Smith f3079d2762 ClangFunction: Fix destruction order of parser and execution unit
Fix PR21802 by correcting the destruction order of
`ClangExpressionParser` and `IRExecutionUnit` in `ClangFunction`.  The
former has hooks into the latter -- i.e., `clang::CGDebugInfo` points at
the `LLVMContext` -- so it needs to be torn down first.

This was exposed by r223802 in LLVM, which started doing work in the
`CGDebugInfo` teardown.

Enrico Granata 0c10a85000 Add the ability for an SBValue to create a persisted version of itself.
Such a persisted version is equivalent to evaluating the value via the expression evaluator, and holding on to the $n result of the expression, except this API can be used on SBValues that do not obviously come from an expression (e.g. are the result of a memory lookup)

Expose this via SBValue::Persist() in our public API layer, and ValueObject::Persist() in the lldb_private layer

Includes testcase

Sean Callanan 9998acd004 This is the meat of the code to add Clang modules
support to LLDB.  It includes the following:

- Changed DeclVendor to TypeVendor.
- Made the ObjCLanguageRuntime provide a DeclVendor
  rather than a TypeVendor.
- Changed the consumers of TypeVendors to use
  DeclVendors instead.
- Provided a few convenience functions on
  ClangASTContext to make that easier.

Jim Ingham 26c7bf9312 Rework the way we pass "run multiple command" options to the various API's that
do that (RunCommandInterpreter, HandleCommands, HandleCommandsFromFile) to gather
the options into an options class.  Also expose that to the SB API's.

Change the way the "-o" options to the lldb driver are processed so:
1) They are run synchronously - didn't really make any sense to run the asynchronously.
2) The stop on error
3) "quit" in one of the -o commands will not quit lldb - not the command interpreter
that was running the -o commands.

I added an entry to the run options to stop-on-crash, but I haven't implemented that yet.

Jason Molenda aff1b357b0 Add a new disassembly-format specification so that the disassembler
output style can be customized.  Change the built-in default to be
more similar to gdb's disassembly formatting.

The disassembly-format for a gdb-like output is

${addr-file-or-load} <${function.name-without-args}${function.concrete-only-addr-offset-no-padding}>: 

The disassembly-format for the lldb style output is

{${function.initial-function}{${module.file.basename}`}{${function.name-without-args}}:\n}{${function.changed}\n{${module.file.basename}`}{${function.name-without-args}}:\n}{${current-pc-arrow} }{${addr-file-or-load}}: 

The two backticks in the lldb style formatter triggers the sub-expression evaluation in
CommandInterpreter::PreprocessCommand() so you can't use that one as-is ... changing to
use ' characters instead of ` would work around that.

Jim Ingham 2bdbfd50d2 This checkin is the first step in making the lldb thread stepping mechanism more accessible from
the user level.  It adds the ability to invent new stepping modes implemented by python classes,
and to view the current thread plan stack and to some extent alter it.

I haven't gotten to documentation or tests yet.  But this should not cause any behavior changes
if you don't use it, so its safe to check it in now and work on it incrementally.

Zachary Turner 97a14e60b2 Move some Host logic into HostInfo class.
This patch creates a HostInfo class, a static class used to answer
basic queries about the host platform.  As part of this change,
some functionality is moved from Host to HostInfo, and relevant
fixups are performed in the rest of the codebase.

This is part of a larger effort to isolate more code in the Host
layer into platform-specific groups, to make it easier to make
platform specific changes for a particular Host without breaking
other hosts.
