We should not be asking unique_file to prepend the system temporary directory
when creating the html report. Unfortunately I don't think we can test this
with the current infrastructure since unique_file ignores MakeAbsolute if the
directory is already absolute and the paths provided by lit are.

I will take a quick look at making this api a bit less error prone.

The operator== calls equivalent which calls default_error_condition which
handles windows to posix conversion.

T **t = new T * ;

This is a better implementation of r183097. The main purpose is to
prevent certain constructs to be formatted "like a block of text".

Before:
aaaaaaaaaaaaa<
    aaaaaaaaaa, aaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa>* aaaa = new aaaaaaaaaaaaa<
    aaaaaaaaaa, aaaaaaaaaaa, aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
    aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa>(bbbbbbbbbbbbbbbbbbbbbbbb);
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa[
    bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb] = (*cccccccccccccccc)[
    dddddddddddddddddddddddddddddddddddddddddddddddddddddddd];

After:
aaaaaaaaaaaaa<aaaaaaaaaa, aaaaaaaaaaa,
              aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
              aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa>* aaaa =
    new aaaaaaaaaaaaa<aaaaaaaaaa, aaaaaaaaaaa,
                      aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa,
                      aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa>(
        bbbbbbbbbbbbbbbbbbbbbbbb);
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa[
    bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb] =
    (*cccccccccccccccc)[
        dddddddddddddddddddddddddddddddddddddddddddddddddddddddd];

Additionally, allow breaking after c-style casts, but with a high
penalty.

Before:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa *foo = (
    aaaaaaaaaaaaaaaaa *)bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb;
After:
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa *foo = (aaaaaaaaaaaaaaaaa *)
    bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb;

Some versions of python will expand the glob used in the test, others wont,
causing the test to fail when run with LIT_USE_INTERNAL_SHELL=1.

This is at least good documentation, but also opens the possibility of
using pipefail.

The test was passing because clang would still print the ast before exiting
with an error. Since that didn't seem to be the intent of the test, I change
the test instead of adding 'not' to the command line.

It was trivially passing because of the tcl quotes and we have better datalayout
tests.

It was not clear what was being tested and the test was trivially passing
by getting grep confused with tcl quotes.

Summary:
Always breaking before multiline strings can help format complex
expressions containing multiline strings more consistently, and avoid consuming
too much horizontal space.

Use SmallVectorImpl instead of SmallVector for iterators and references to avoid specifying the vector size unnecessarily.

The motivation is to suppresses false use-after-free reports that occur when calling
std::list::pop_front() or std::list::pop_back() twice. The analyzer does not
reason about the internal invariants of the list implementation, so just do not report
any of warnings in std::list.

substitution failed, report that as a substitution failure rather than
pretending that there was no default argument.

The test cases in PR15673 have exposed some pre-existing poor diagnostics here.
