Checking if they evaluate to true cases prevents passing values that evaluate to false cases. Instead we should check if the variables are defined.

Summary:
This patch adds a CMake option LLDB_BUILD_FRAMEWORK, which builds libLLDB as a macOS framework instead of as a *nix shared library.
With this patch any LLDB executable that has the INCLUDE_IN_FRAMEWORK option set will be built into the Framework's resources directory, and a symlink to the exeuctable will be placed under the build directory's bin folder. Creating the symlinks allows users to run commands from the build directory without altering the workflow.
The framework generated by this patch passes the LLDB test suite, but has not been tested beyond that. It is not expected to be fully ready to ship, but it is a first step.
With this patch binaries that are placed inside the framework aren't being properly installed. Fixing that would increase the patch size significantly, so I'd like to do that in a follow-up.

Summary:
Finish work on PR30351 (last one, after D24551, D24552, and D24554 land)
Also replace the old ReportData structure/variable with the current_error_ static
member of the ScopedInErrorReport class.
This has the following side-effects:
- Move ASAN_ON_ERROR(); call to the start of the destructor, instead
of in StartReporting().
- We only generate the error structure after the
ScopedInErrorReport constructor finishes, so we can't call
ASAN_ON_ERROR() during the constructor. I think this makes more
sense, since we end up never running two of the ASAN_ON_ERROR()
callback. This also works the same way as error reporting, since
we end up having a lock around it. Otherwise we could end up
with the ASAN_ON_ERROR() call for error 1, then the
ASAN_ON_ERROR() call for error 2, and then lock the mutex for
reporting error 1.
- The __asan_get_report_* functions will be able to, in the future,
provide information about other errors that aren't a "generic
error". But we might want to rethink that API, since it's too
restricted. Ideally we teach lldb about the current_error_ member of
ScopedInErrorReport.

This change introduces optional marking of the column within a source
line where a thread is stopped. This marking will show up when the
source code for a thread stop is displayed, when the debug info
knows the column information, and if the optional column marking is
enabled.
There are two separate methods for handling the marking of the stop
column:
* via ANSI terminal codes, which are added inline to the source line
display. The default ANSI mark-up is to underline the column.
* via a pure text-based caret that is added in the appropriate column
in a newly-inserted blank line underneath the source line in
question.
There are some new options that control how this all works.
* settings set stop-show-column
This takes one of 4 values:
* ansi-or-caret: use the ANSI terminal code mechanism if LLDB
is running with color enabled; if not, use the caret-based,
pure text method (see the "caret" mode below).
* ansi: only use the ANSI terminal code mechanism to highlight
the stop line. If LLDB is running with color disabled, no
stop column marking will occur.
* caret: only use the pure text caret method, which introduces
a newly-inserted line underneath the current line, where
the only character in the new line is a caret that highlights
the stop column in question.
* none: no stop column marking will be attempted.
* settings set stop-show-column-ansi-prefix
This is a text format that indicates the ANSI formatting
code to insert into the stream immediately preceding the
column where the stop column character will be marked up.
It defaults to ${ansi.underline}; however, it can contain
any valid LLDB format codes, e.g.
${ansi.fg.red}${ansi.bold}${ansi.underline}
* settings set stop-show-column-ansi-suffix
This is the text format that specifies the ANSI terminal
codes to end the markup that was started with the prefix
described above. It defaults to: ${ansi.normal}. This
should be sufficient for the common cases.
Significant leg-work was done by Adrian Prantl. (Thanks, Adrian!)

Currently, we give up on loop interchange if we encounter a flow dependency
anywhere in the loop list. Worse yet, we don't even track output dependencies.
This patch updates the dependency matrix computation to track flow and output
dependencies in the same way we track anti dependencies.
This improves an internal workload by 2.2x.
Note the loop interchange pass is off by default and it can be enabled with
'-mllvm -enable-loopinterchange'

With the new LTO API in r278338, we stopped emitting the individual
index files and imports files for some modules in the distributed backend
case (thinlto-index-only plugin option).
Specifically, this is when the linker decides not to include a module in the
link, because it was in an archive library and did not have a strong
reference to it. Not creating the expected output files makes the
distributed build system implementation more difficult, in terms of
checking for the expected outputs of the thin link, and scheduling the
backend jobs. To address this, the gold-plugin will write dummy empty
.thinlto.bc and .imports files for modules not included in the link
(which LTO never sees).
Augmented a gold v1.12+ test, since that version of gold has the handling
for notifying on modules not being included in the link.

The actual logic is to keep the output section if the output section
would have been ro/rw.
This is both simpler and more practical, as the intention is linker
scripts is to always keep of of a pair of ONLY_IF_RO/ONLY_IF_RW.

r282079 converted the regular expression interface to accept
and return StringRefs instead of char pointers. In one case
a null pointer check was converted to an empty string check,
but this was an incorrect conversion because an empty string
is a valid regular expression. Removing this check should
fix the test failures.

If we identify an instruction as uniform after vectorization, we know that we
should only use the value corresponding to the first vector lane of each unroll
iteration. However, when scalarizing such instructions, we still produce values
for the other vector lanes. This patch prevents us from generating the unused
scalars.

Summary:
The dynamic shadow code is not detected correctly on Android.
The android shadow seems to start at address zero.
The bug is introduced here:
https://reviews.llvm.org/D23363
Started here: https://build.chromium.org/p/chromium.fyi/builders/ClangToTAndroidASan/builds/4029
Likely due to an asan runtime change, filed https://llvm.org/bugs/show_bug.cgi?id=30462
From asan_mapping.h:
```
#if SANITIZER_WORDSIZE == 32
# if SANITIZER_ANDROID
# define SHADOW_OFFSET (0) <<---- HERE
# elif defined(__mips__)
```
Shadow address on android is 0.
From asan_rtl.c:
```
if (shadow_start == 0) {
[...]
shadow_start = FindAvailableMemoryRange(space_size, alignment, granularity);
}
```
We assumed that 0 is dynamic address.
On windows, the address was determined with:
```
# elif SANITIZER_WINDOWS64
# define SHADOW_OFFSET __asan_shadow_memory_dynamic_address
# else
```
and __asan_shadow_memory_dynamic_address is initially zero.

This is PR30442.
Previously we were failed to parce complex expressions like:
foo : { *(SORT_BY_NAME(bar) zed) }
Main idea of patch that globs and excludes can be wrapped in a SORT.
There is a difference in semanics of ld/gold:
ld likes:
*(SORT(EXCLUDE_FILE (*file1.o) .foo.1))
gold likes:
*(EXCLUDE_FILE (*file1.o) SORT(.foo.1))
Patch implements ld grammar, complex expressions like
next is not a problem anymore:
.abc : { *(SORT(.foo.* EXCLUDE_FILE (*file1.o) .bar.*) .bar.*) }
