Shiva Chen 2c864551df [DebugInfo] Add DILabel metadata and intrinsic llvm.dbg.label.
In order to set breakpoints on labels and list source code around
labels, we need collect debug information for labels, i.e., label
name, the function label belong, line number in the file, and the
address label located. In order to keep these information in LLVM
IR and to allow backend to generate debug information correctly.
We create a new kind of metadata for labels, DILabel. The format
of DILabel is

!DILabel(scope: !1, name: "foo", file: !2, line: 3)

We hope to keep debug information as much as possible even the
code is optimized. So, we create a new kind of intrinsic for label
metadata to avoid the metadata is eliminated with basic block.
The intrinsic will keep existing if we keep it from optimized out.
The format of the intrinsic is

llvm.dbg.label(metadata !1)

It has only one argument, that is the DILabel metadata. The
intrinsic will follow the label immediately. Backend could get the
label metadata through the intrinsic's parameter.

We also create DIBuilder API for labels to be used by Frontend.
Frontend could use createLabel() to allocate DILabel objects, and use
insertLabel() to insert llvm.dbg.label intrinsic in LLVM IR.

Summary: Add bindings to create import declarations for modules, functions, types, and other entities.  This wraps the conveniences available in the existing DIBuilder API, but these seem C++-specific.

Reid Kleckner 2fe905cfee Fix go bindings test when using goma distributed build tool
Goma[1] is a distributed build system similar to distcc and icecc
primarily used to compile Chromium. The client is open source, and
hopefully soon the server will be as well. The intended usage model is
similar to most distributed build systems: prefix gomacc onto your
compiler command line, and it transparently distributes compilation.

The go lit config wants to determine the host compiler binary, so it
needs some extra logic to avoid looking at these prefixes.

Though it is unlikely LLVM will gain more supported global value linker
hints, the new API can scale to accommodate this.

Kuba Mracek 17ee427ef3 [llvm] Get rid of "%T" expansions
The %T lit expansion expands to a common directory shared between all the tests in the same directory, which is unexpected and unintuitive, and more importantly, it's been a source of subtle race conditions and flaky tests. In https://reviews.llvm.org/D35396, it was agreed that it would be best to simply ban %T and only keep %t, which is unique to each test. When a test needs a temporary directory, it can just create one using mkdir %t.

This patch removes %T in llvm.

Michal Gorny 9283f5b200 [cmake] Canonicalize CMake booleans to 0/1 for lit interop
Canonicalize all CMake booleans to 0/1 before passing them to lit, to
ensure that the Python side handles all of them consistently
and correctly. 0/1 is a safe choice of values that trigger the same
boolean interpretation in CMake, Python and C++.

Furthermore, using them without quotes improves the chance Python will
explicitly fail when an incorrect value (such as ON/OFF, TRUE/FALSE,
YES/NO) is accidentally passed, rather than silently misinterpreting
the value.

This replaces a lot of different logics spread around lit site files,
attempting to partially reproduce the boolean logic used in CMake
and usually silently failing when an uncommon value was used instead.
In fact, some of them were never working correctly since different
values were assigned in CMake and checked in Python.

The alternative solution could be to create a common parser for CMake
booleans in lit and use it consistently throughout the site files.
However, it does not seem like the best idea to create redundant
implementation of the same logic and have to follow upstream if it ever
is extended to handle more values.
