Currently, we ignore all dso locality attributes/info when building for
the device and thus all symblos are externally visible and can be
preemted at the runtime. It may lead to incorrect results. We need to
follow the same logic, compiler uses for static/pie builds.

Summary:
This commit moves the logic for determining system, resource and C++
header search paths from CC1 to the driver. This refactor has already
been made for several platforms, but Darwin had been left behind.
This refactor tries to implement the previous search path logic with
perfect accuracy. In particular, the order of all include paths inside
CC1 and all paths that were skipped because nonexistent are conserved
after the refactor. This change was also tested against a code base
of significant size and revealed no problems.

When a preamble is created an unsaved file not existing on disk is
already part of PrecompiledPreamble::FilesInPreamble. However, when
checking whether the preamble can be re-used, a failed stat of such an
unsaved file invalidated the preamble, which led to pointless and time
consuming preamble regenerations on subsequent reparses.
Do not require anymore that unsaved files should exist on disk.
This avoids costly preamble invalidations depending on timing issues for
the cases where the file on disk might be removed just to be regenerated
a bit later.
It also allows an IDE to provide in-memory files that might not exist on
disk, e.g. because the build system hasn't generated those yet.

message sends, designators, and attributes.
Instead of having the tentative parsing phase sometimes return an
indicator to say what diagnostic to produce if parsing fails and
sometimes ask the caller to run it again, consistently ask the caller to
try parsing again if tentative parsing would fail or is otherwise unable
to completely parse the lambda-introducer without producing an
irreversible semantic effect.
Mostly NFC, but we should recover marginally better in some error cases
(avoiding duplicate diagnostics).

We shouldn't really make assumptions about possible sizes for long and long long. And longer term we should probably support vectorizing these intrinsics. By making the result types not fixed we can support vectors as well.

Summary:
The RangeSelector library defines a combinator language for specifying source
ranges based on bound ids for AST nodes. The combinator approach follows the
design of the AST matchers. The RangeSelectors defined here will be used in
both RewriteRule, for specifying source affected by edit, and in Stencil for
specifying source to use constructively in a replacement.

TokenBuffer stores the list of tokens for a file obtained after

This commits also starts a new sub-library of ClangTooling, which
would be the home for the syntax trees and syntax-tree-based refactoring
utilities.

This patch refactors begin and end symbol creation by moving symbol
conjuration into the `create...` functions. This way the functions'
responsibilities are clearer and makes possible to add more functions
handling these symbols (e.g. functions for handling the container's
size) without code multiplication.

Summary:
This patch modifies the AVR toolchain so that if avr-gcc and avr-libc
are detected during compilation, the CRT, libgcc, libm, and libc anre
linked.
This matches avr-gcc's default behaviour, and the expected behaviour of
all C compilers - including the C runtime.
avr-gcc also needs a -mmcu specified in order to link runtime libraries.
The difference betwen this patch and avr-gcc is that this patch will
warn users whenever they compile without a runtime, as opposed to GCC,
which silently trims the runtime libs from the linker arguments when no
-mmcu is specified.

Since D57922, the config table contains every checker option, and it's default
value, so having it as an argument for getChecker*Option is redundant.
By the time any of the getChecker*Option function is called, we verified the
value in CheckerRegistry (after D57860), so we can confidently assert here, as
any irregularities detected at this point must be a programmer error. However,
in compatibility mode, verification won't happen, so the default value must be
restored.
This implies something else, other than adding removing one more potential point
of failure -- debug.ConfigDumper will always contain valid values for
checker/package options!

This revision updates `RewriteRule` to support multiple subrules that are
interpreted as an ordered-choice (apply the first one that matches). With this
feature, users can write the rules that appear later in the list of subrules
knowing that previous rules' patterns *have not matched*, freeing them from
reasoning about those cases in the current pattern.
