Fix handling of double quotes (MI)
Summary:
* Clean CMICmdArgValString::Validate: now it's based on CMIUtilString::SplitConsiderQuotes method:
A bit of introduction:
# Command line is wrapped into CMICmdArgContext.
# CMICmdArgSet is a set of arguments to be parsed. This class contains CMICmdArgContext as a private member.
# MI command is class which is inhereted from CMICmdBase. It contains CMICmdArgSet as a private member.
When command is executed CMICmdBase::ParseArgs() is called. This method adds args for parsing using CMICmdArgSet::Add(). Then CMICmdBase::ParseValidateCmdOptions() is called, which calls CMICmdArgSet::Validate(). Then it gets a number of arguments (using SplitConsiderQuotes().array_length) and for each arguments registered in ParseArgs() tries to validate it using CMICmdArgValBase::Validate(). Every user commands parses this string again (first time it was made in SplitConsiderQuotes) and in case of CMICmdArgValString it was made incorrectly. It searches the first and last quotes (but it should be first and next after first). Besides, it was splitted into 4 cases.
I'm just using SplitConsiderQuotes directly, and I don't split them by hand again.
Actually, I think we should do so in every CMICmdArgVal_XXX::Validate() method.
* Enable MiInterpreterExecTestCase.test_lldbmi_target_create test
* Fix MiExecTestCase.test_lldbmi_exec_arguments_set test

FileCheck: Add CHECK-SAME

line as the previous `CHECK`/`CHECK-NEXT` -- in other words, no newline

which requires exactly 1 newline in the skipped region.
My motivation is to simplify checking the long lines of LLVM assembly
for the new debug info hierarchy. This allows CHECK sequences like the
following:
CHECK: ![[REF]] = !SomeMDNode(
CHECK-SAME: file: ![[FILE:[0-9]+]]
CHECK-SAME: otherField: 93{{[,)]}}

CHECK: ![[REF]] = !SomeMDNode({{.*}}file: ![[FILE:[0-9]+]]{{.*}}otherField: 93{{[,)]}}
While this example just has two fields, many nodes in debug info have
more than that. `CHECK-SAME` will keep the logic easy to follow.
Morever, it enables interleaving `CHECK-NOT`s without allowing newlines.
Consider the following:
CHECK: ![[REF]] = !SomeMDNode(
CHECK-SAME: file: ![[FILE:[0-9]+]]

Add remote testing support to the lit config.
Executors can be specified at configure time by using the -DLIBCXX_EXECUTOR=""
option. Examples include:
$ cmake <other_flags> -DLIBCXX_EXECUTOR="TimeoutExecutor(30,LocalExecutor())"
This runs individual tests with a maximum duration
$ cmake <other_flags> -DLIBCXX_EXECUTOR="SSHExecutor('hostname','username')"
This runs tests on a remote target, using scp to shuttle binaries to the
target, and ssh to invoke commands there.
$ cmake <other_flags> -DLIBCXX_EXECUTOR="PrefixExecutor('/path/to/run/script',LocalExecutor())"
This assumes the script knows how to copy run the executables passed to it,
and allows for the ultimate control. This is useful for running things
inside emulators like Valgrind & QEMU.
TODO: This doesn't claim to support ShTest tests yet, that will take a bit more
thought & finagling (I'm still not sure how to orchestrate copy-in for those cases.
I've also punted on what to do about tests that read data files. The testsuite
has several tests that need to read *.dat files placed next to them, and
currently those aren't copied over when using, say, an SSHExecutor. The
affected tests are:
libc++ :: std/input.output/file.streams/fstreams/filebuf.virtuals/pbackfail.pass.cpp
libc++ :: std/input.output/file.streams/fstreams/filebuf.virtuals/underflow.pass.cpp

Note: One thing to watch out for when using the SSHExecutor for cross-testing is
that you'll also want to specify a TargetInfo object (so that the host's
features aren't used for available-features checks and flags setup).

Optimize finding the Complete Definition of an ObjC class for debug with .o files with lots of .o files.
When we have a debug map we have an executable with a bunch of STAB symbols and each source file has a N_SO symbol which scopes a bunch of symbols inside of it. We can use this to our advantage here when looking for the complete definition of an objective C class by looking for a symbol whose name matches the class name and whose type is eSymbolTypeObjCClass. If we find one, that symbol will be contained within a N_SO symbol. This symbol gets turned into a symbol whose type is eSymbolTypeSourceFile and that symbol will contain the eSymbolTypeObjCClass which helps us to locate the correct .o file and allows us to only look in that file.
To further accelerate things, if we are looking for the implementation, we can avoid looking at all .o files if we don't find a matching symbol because we have a debug map, which means the objective C symbol for the class can't have been stripped, so we can safely not search all remaining .o files. This will save us lots of time when trying to look for "NSObject" and any other AppKit and Foundation classes that we never have implementation definitions for.

Summary: SROA generates code that isn't quite as easy to optimize and contains unusual-sized shuffles, but that code is generally correct.
