LLDB included editline in a couple of places, not respecting LLDB_DISABLE_LIBEDIT. As far as I can tell, these includes are not used, so I am removing them.

Linking the debug frame section is actually very easy as we just have to
patch the start address in the FDE header and then copy the rest of the
FDE without even looking at it. The only small complexity comes from the
handling of the CIEs that we should unique across object file. This is
also really easy by using a StringMap keyed on the raw contents of the
CIE.

It's better not to rely on the diagnostics engine to pretty print the
argument to decltype. Instead, exercise the functionality in
DeclPrinterTest.

Summary:
Update DYLDRendezvous and SOEntry to use FileSpecs instead of storing paths as
strings, which caused incorrect comparison results due to denormalization.

the overloaded version of addPass which takes Pass*.
This change enables inserting the machine printer pass when the overloaded
version of addPass that takes Pass* is called to add a pass, instead of the
one which takes AnalysisID. I need this to prevent make-check tests from
failing when I commit another patch later.

The main use of the YAML debug map format is for testing inside LLVM. If we have IR
files in the tests used to generate object files, then we obviously don't know the
addresses of the symbols inside the object files beforehand.
This change lets the YAML import lookup the addresses in the object files and rewrite
them. This will allow to have test that really don't need any binary input.

Summary: This fixes the issue of multiple test suites opening the same file for writing.

It will get a bit bigger in an upcoming commit. No need to have all
of that in the header.
Also move parseYAMLDebugMap() to the same place as the serialization
code. This way it will be able to share a private Context object with
it.

when compiling with gcc or clang numerous warnings concerning the usage
of extern "C" linkage. All the __kmp_itt_sync* variables are declared
like: extern "C" type __kmp_itt_sync... = definition; through various macros.
This note from cppreference.com explains why this is a problem.
// From http://en.cppreference.com/w/cpp/language/language_linkage
extern "C" int x; // a declaration and not a definition
// The above line is equivalent to extern "C" { extern int x; }
extern "C" { int x; } // a declaration and definition
Since the __kmp_itt_* variables are being declared and defined, these variables
should use the bracketed version instead.

This test case uses too large addends in relocations. Now the test is correct.
Later we need to implement overflow checking to catch such cases.

This reverts commit r239141. This commit was an attempt to reintroduce
a previous patch that broke many self-hosting bots with clang timeouts,
but it still has slowdown issues, at least on ARM, increasing the
compilation time (stage 2, clang's) by 5x.

Summary:
urlparse.ParseResult.hostname has only lowercase characters even if the
input URL had uppercase characters. Since Android device IDs can have
uppercase characters as well, use urlparse.ParseResult.netloc instead
and extract the device ID from it.
This change also improves the error message when lookup of the Android
device's API fails.

This change is NFC because both the ``break;`` and the fall through end
up returning immediately. However, this helps clarify intent and also
ensures correctness in case more ``case`` blocks are added later.

We would crash in the DeclPrinter trying to pretty-print the
static_assert message. C++1z-style assertions don't have a message so
we would crash.
This fixes PR23756.

For targets with a free fneg, this fold is always a net loss if it
ends up duplicating the multiply, so definitely avoid it.
This might be true for some targets without a free fneg too, but
I'll leave that for future investigation.

The new naming is (to me) much easier to understand. Here is a summary
of the new state of the world:
- '*Threshold' is the threshold for full unrolling. It is measured
against the estimated unrolled cost as computed by getUserCost in TTI
(or CodeMetrics, etc). We will exceed this threshold when unrolling
loops where unrolling exposes a significant degree of simplification
of the logic within the loop.
- '*PercentDynamicCostSavedThreshold' is the percentage of the loop's
estimated dynamic execution cost which needs to be saved by unrolling
to apply a discount to the estimated unrolled cost.
- '*DynamicCostSavingsDiscount' is the discount applied to the estimated
unrolling cost when the dynamic savings are expected to be high.
When actually analyzing the loop, we now produce both an estimated
unrolled cost, and an estimated rolled cost. The rolled cost is notably
a dynamic estimate based on our analysis of the expected execution of
each iteration.
While we're still working to build up the infrastructure for making
these estimates, to me it is much more clear *how* to make them better
when they have reasonably descriptive names. For example, we may want to
apply estimated (from heuristics or profiles) dynamic execution weights
to the *dynamic* cost estimates. If we start doing that, we would also
need to track the static unrolled cost and the dynamic unrolled cost, as
only the latter could reasonably be weighted by profile information.
This patch is sadly not without functionality change for the new unroll
analysis logic. Buried in the heuristic management were several things
that surprised me. For example, we never subtracted the optimized
instruction count off when comparing against the unroll heursistics!
I don't know if this just got lost somewhere along the way or what, but
with the new accounting of things, this is much easier to keep track of
and we use the post-simplification cost estimate to compare to the
thresholds, and use the dynamic cost reduction ratio to select whether
we can exceed the baseline threshold.
The old values of these flags also don't necessarily make sense. My
impression is that none of these thresholds or discounts have been tuned
yet, and so they're just arbitrary placehold numbers. As such, I've not
bothered to adjust for the fact that this is now a discount and not
a tow-tier threshold model. We need to tune all these values once the
logic is ready to be enabled.
