Summary:
With this change, we allow someone to chose the `SizeClassMap` they want to use
at compile time via a define.
I feel somewhat unimaginative with the name of the defines, so if someone has a
better idea, let me know. I have been alternating between those and
`SCUDO_USE_xxx_SIZECLASSMAP` which is clearer but also longer. The issue with
those is that it wouldn't be consistent with `SCUDO_TSD_EXCLUSIVE` that should
probably become `SCUDO_USE_EXCLUSIVE_TSD` maybe?
Anyway, naming is hard, and I am not sure what makes more sense!

It looks FindDynamicShadowStart has a bug: When iterating over the memory map, we will not consider the very last gap in the address space. Let's fix that.

It's explicitly forbidden to call fclose with NULL, but at least on Darwin, this succeeds and doesn't segfault. To maintain binary compatibility, ASan should survice fclose(NULL) as well.

A couple of places in LLD were passing references to
TypeTableCollections around, which makes it hard to change the
implementation at runtime. However, these cases only needed to
iterate over the types in the collection, and TypeCollection
already provides a handy abstract interface for this purpose.
By implementing this interface, we can get rid of the need to
pass TypeTableBuilder references around, which should allow us
to swap the implementation at runtime in subsequent patches.

Calling getpwnam(NULL) is probably a bug, but at least on Darwin, such a call succeeds without segfaulting. I have some existing code that relies on that. To maintain binary compatibility, ASan should also survive a call to getpwnam with NULL.

The code for the two OpenMP runtime libraries was very similar.
Move to common CMake file that is included and provides a simple
interface for adding testsuites. Also add a common check-openmp
target that runs all testsuites that have been registered.
Note that this renames all test options to the common OPENMP
namespace, for example OPENMP_TEST_C_COMPILER instead of
LIBOMP_TEST_COMPILER and so on.

These are needed by both libraries, so we can do that in a
common namespace and unify configuration parameters.
Also make sure that the user isn't requesting libomptarget
if the library cannot be built on the system. Issue an error
in that case.

This renames ASM_TSAN_SYMBOL and ASM_TSAN_SYMBOL_INTERCEPTOR to just ASM_SYMBOL and ASM_SYMBOL_INTERCEPTOR, because they can be useful in more places than just TSan. Also introduce a CMake function to add ASM sources to a target.

This warning is known to be noisy and projects frequently disable it. In
particular, this should make building isl as bundled in polly with

In the original design of the analyzer, it was assumed that a BlockEntrance
doesn't create a new binding on the Store, but this assumption isn't true when
'widen-loops' is set to true. Fix this by finding an appropriate location

Instead, reuse the code-path for cl.exe that adds /W4 , which for clang-cl
aliases clang's "-Wall -Wextra" which matches what clang-cl's /Wall
previously aliased.
This should restore the verbosity of a Windows selfhost build back to
its previous levels.

Detects whether we have the Python modules (pygments, yaml) required by
opt-viewer and hooks this up to REQUIRES.
This fixes https://bugs.llvm.org/show_bug.cgi?id=34129 (the lack of opt-viewer
testing).
It's also related to https://github.com/apple/swift/pull/12938 and the idea is
to expose LLVM_HAVE_OPT_VIEWER_MODULES to the Swift cmake.

This fixes some bugs in the reflowing logic and splits out the concerns
of reflowing from BreakableToken.
Things to do after this patch:
- Refactor the breakProtrudingToken function possibly into a class, so we
can split it up into methods that operate on the common state.
- Optimize whitespace compression when reflowing by using the next possible
split point instead of the latest possible split point.
- Retry different strategies for reflowing (strictly staying below the
column limit vs. allowing excess characters if possible).

When lowering a G_BRCOND, we generate a TSTri of the condition against
1, which sets the flags, and then a Bcc which branches based on the
value of the flags.
Unfortunately, we were using the wrong condition code to check whether
we need to branch (EQ instead of NE), which caused all our branches to
do the opposite of what they were intended to do. This patch fixes the
issue by using the correct condition code.

Summary:
This makes the parse() functions about as short as they can be given the
current signature, and moves all array-traversal etc code to a
central location.
We keep the ability to distinguish between optional and required fields:
and we don't propagate parse errors for optional fields.
I've made most fields required per the LSP spec - the looseness we had
here was mostly a historical accident I think.

The AArch64 unconditional branch and branch and link instructions have a
maximum range of 128 Mib. This is usually enough for most programs but
there are cases when it isn't enough. This change adds support for range
extension thunks to AArch64. For pc-relative thunks we follow the small
code model and use ADRP, ADD, BR. This has a limit of 4 gigabytes.
