Retrieve a function PDB symbol correctly from nested blocks
Summary:
This patch fixes a problem with retrieving a function symbol by an address in a nested block. In the current implementation of ResolveSymbolContext function it retrieves a symbol with PDB_SymType::None and then checks if found symbol's tag equals to PDB_SymType::Function. So, if nested block's symbol was found, ResolveSymbolContext does not resolve a function.
It is very simple to reproduce this. For example, in the next program
```
int main() {
auto r = 0;
for (auto i = 1; i <= 10; i++) {
r += i & 1 + (i - 1) & 1 - 1;
}
return r;
}
```
if we will stop inside the cycle and will do a backtrace, the top element will be broken. But how we can test this? I thought to add an option to lldb-test to allow search a function by address, but the address may change when the compiler will be changed.

This is a partial fix. To make this review easier, I did not make changes for the single binop

[PM/Unswitch] Fix a nasty bug in the new PM's unswitch introduced in
r335553 with the non-trivial unswitching of switches.
The code correctly updated most aspects of the CFG and analyses, but
missed some crucial aspects:
1) When multiple cases have the same successor, we unswitch that
a single time and replace the switch with a direct branch. The CFG
here is correct, but the target of this direct branch may have had
a PHI node with multiple entries in it.
2) When we still have to clone a successor of the switch into an
unswitched copy of the loop, we'll delete potentially multiple edges
entering this successor, not just one.
3) We also have to delete multiple edges entering the successors in the
original loop when they have to be retained.
4) When the "retained successor" *also* occurs as a case successor, we
just assert failed everywhere. This doesn't happen very easily
because its always valid to simply drop the case -- the retained
successor for switches is always the default successor. However, it
is likely possible through some contrivance of different loop passes,
unrolling, and simplifying for this to occur in practice and
certainly there is nothing "invalid" about the IR so this pass needs
to handle it.
5) In the case of #4, we also will replace these multiple edges with
a direct branch much like in #1 and need to collapse the entries in
any PHI nodes to a single enrty.
All of this stems from the delightful fact that the same successor can
show up in multiple parts of the switch terminator, and each of these
are considered a distinct edge for the purpose of PHI nodes (and
iterating the successors and predecessors) but not for unswitching
itself, the dominator tree, or many other things. For the record,
I intensely dislike this "feature" of the IR in large part because of
the complexity it causes in passes like this. We already have a ton of
logic building sets and handling duplicates, and we just had to add
a bunch more.
I've added a complex test case that covers all five of the above failure
modes. I've also added a variation on it where #4 and #5 occur in loop
exit, adding fun where we have an LCSSA PHI node with "multiple entries"
despite have dedicated exits. There were no additional issues found by
this, but it seems a useful corner case to cover with testing.
One thing that working on all of this code has made painfully clear for
me as well is how amazingly inefficient our PHI node representation is
(in terms of the in-memory data structures and the APIs used to update
them). This code has truly marvelous complexity bounds because every
time we remove an entry from a PHI node we do a linear scan to find it
and then a linear update to the data structure to remove it. We could in
theory batch all of the PHI node updates into a single linear walk of
the operands making this much more efficient, but the APIs fight hard
against this and the fact that we have to handle duplicates in the
peculiar manner we do (removing all but one in some cases) makes even
implementing that very tedious and annoying. Anyways, none of this is
new here or specific to loop unswitching. All code in LLVM that updates
PHI node operands suffers from these problems.

Lift JSON library from clang-tools-extra/clangd to llvm/Support.
Summary:
This consists of four main parts:
- an type json::Expr representing JSON values of dynamic kind, which can be
composed, inspected, and modified
- a JSON parser from string -> json::Expr
- a JSON printer from json::Expr -> string, with optional pretty-printing
- a convention for mapping json::Expr <=> native types (fromJSON/toJSON)
Mapping functions are provided for primitives (e.g. int, vector) and the
ObjectMapper helper helps implement fromJSON for struct/object types.
Based on clangd's usage, a couple of places I'd appreciate review attention:
- fromJSON returns only bool. A richer error-signaling mechanism may be useful
to provide useful messages, or let recursive fromJSONs (containers/structs)
do careful error recovery.
- should json::obj be always explicitly written (like json::ary)
- there's no streaming parse API. I suspect there are some simple wins like
a callback API where the document is a long array, and each element is small.
But this can probably be bolted on easily when we see the need.

[PM/LoopUnswitch] Fix PR37889, producing the correct loop nest structure
after trivial unswitching.
This PR illustrates that a fundamental analysis update was not performed
with the new loop unswitch. This update is also somewhat fundamental to
the core idea of the new loop unswitch -- we actually *update* the CFG
based on the unswitching. In order to do that, we need to update the
loop nest in addition to the domtree.
For some reason, when writing trivial unswitching, I thought that the
loop nest structure cannot be changed by the transformation. But the PR
helps illustrate that it clearly can. I've expanded this to a number of
different test cases that try to cover the different cases of this. When
we unswitch, we move an exit edge of a loop out of the loop. If this
exit edge changes which loop reached by an exit is the innermost loop,
it changes the parent of the loop. Essentially, this transformation may
hoist the inner loop up the nest. I've added the simple logic to handle
this reliably in the trivial unswitching case. This just requires
updating LoopInfo and rebuilding LCSSA on the impacted loops. In the
trivial case, we don't even need to handle dedicated exits because we're
only hoisting the one loop and we just split its preheader.
I've also ported all of these tests to non-trivial unswitching and
verified that the logic already there correctly handles the loop nest
updates necessary.

[OPENMP] Fix PR38026: Link -latomic when -fopenmp is used.

Fix DIExpression::ExprOperand::appendToVector
appendToVector used the wrong overload of SmallVector::append, resulting
in it appending the same element to a vector `getSize()` times. This did
not cause a problem when initially committed because appendToVector was
only used to append 1-element operands.
This changes appendToVector to use the correct overload of append().
Testing: ./unittests/IR/IRTests --gtest_filter='*DIExpressionTest*'

Remove a redundant null-check in DIExpression::prepend, NFC
Code outside of an `if (Expr)` block dereferenced `Expr`, so the null
check was redundant.

[PDB] One more fix for hasing GSI records.
The reference implementation uses a case-insensitive string
comparison for strings of equal length. This will cause the
string "tEo" to compare less than "VUo". However we were using
a case sensitive comparison, which would generate the opposite
outcome. Switch to a case insensitive comparison. Also, when
one of the strings contains non-ascii characters, fallback to
a straight memcmp.
The only way to really test this is with a DIA test. Before this
patch, the test will fail (but succeed if link.exe is used instead
of lld-link). After the patch, it succeeds even with lld-link.

[test-suite] Add a decorator for the lack of libstdcxx on the system.
This generalizes a bunch of target-specific tests. MacOS has no
libstdcxx anymore, and neither does FreeBSD (or Windows).

Use Type::isIntOrPtrTy where possible, NFC
It's a bit neater to write T.isIntOrPtrTy() over `T.isIntegerTy() ||
T.isPointerTy()`.
I used Python's re.sub with this regex to update users:
r'([\w.\->()]+)isIntegerTy\(\)\s*\|\|\s*\1isPointerTy\(\)'
