[NFC] Refactor DiagnosticBuilder and PartialDiagnostic

PartialDiagnostic misses some functions compared to DiagnosticBuilder.

This patch refactors DiagnosticBuilder and PartialDiagnostic, extracts
the common functionality so that the streaming << operators are
shared.

[libunwind] Support for leaf function unwinding.

Unwinding leaf function is useful in cases when the backtrace finds a
leaf function for example when it caused a signal.
This patch also add the support for the DW_CFA_undefined because it marks
the end of the frames.

Ryan Prichard provided code for the tests.

Commit dd3eb3f33239b23a12dd8864ae236390adf79550 by psteinfeld
[flang] Substrings with lower bound greater than upper bound

According to section 9.4.1, paragraph 3,
If the starting point is greater than the ending point, the substring has
length zero

But the compilers code for substring processing was failing a call to `CHECK()`
in this case.  I fixed this by just setting the number of items in the
resulting string to 0 for this situation.

Disable a large test for EXPENSIVE_CHECKS and debug build

Summary:
When running a large test in LLVM_ENABLE_EXPENSIVE_CHECKS=ON mode,
buildbot could hit timeout.
Disable the test when this mode is on.
Also disable it for debug so that the test won't hang for too long.
