[analyzer] Fix the liveness of Symbols for values in regions referred by LazyCompoundVal
To illustrate our current understanding, let's start with the following program:
https://godbolt.org/z/33f6vheh1
```lang=c++
void clang_analyzer_printState();
struct C {
int x;
int y;
int more_padding;
};
struct D {
C c;
int z;
};
C foo(D d, int new_x, int new_y) {
d.c.x = new_x; // B1
assert(d.c.x < 13); // C1
C c = d.c; // L
assert(d.c.y < 10); // C2
assert(d.z < 5); // C3
d.c.y = new_y; // B2
assert(d.c.y < 10); // C4
return c; // R
}
```
In the code, we create a few bindings to subregions of root region `d` (`B1`, `B2`), a constrain on the values (`C1`, `C2`, ….), and create a `lazyCompoundVal` for the part of the region `d` at point `L`, which is returned at point `R`.
Now, the question is which of these should remain live as long the return value of the `foo` call is live. In perfect a word we should preserve:
# only the bindings of the subregions of `d.c`, which were created before the copy at `L`. In our example, this includes `B1`, and not `B2`. In other words, `new_x` should be live but `new_y` shouldn’t.
# constraints on the values of `d.c`, that are reachable through `c`. This can be created both before the point of making the copy (`L`) or after. In our case, that would be `C1` and `C2`. But not `C3` (`d.z` value is not reachable through `c`) and `C4` (the original value of`d.c.y` was overridden at `B2` after the creation of `c`).
The current code in the `RegionStore` covers the use case (1), by using the `getInterestingValues()` to extract bindings to parts of the referred region present in the store at the point of copy. This also partially covers point (2), in case when constraints are applied to a location that has binding at the point of the copy (in our case `d.c.x` in `C1` that has value `new_x`), but it fails to preserve the constraints that require creating a new symbol for location (`d.c.y` in `C2`).
We introduce the concept of //lazily copied// locations (regions) to the `SymbolReaper`, i.e. for which a program can access the value stored at that location, but not its address. These locations are constructed as a set of regions referred to by `lazyCompoundVal`. A //readable// location (region) is a location that //live// or //lazily copied// . And symbols that refer to values in regions are alive if the region is //readable//.
For simplicity, we follow the current approach to live regions and mark the base region as //lazily copied//, and consider any subregions as //readable//. This makes some symbols falsy live (`d.z` in our example) and keeps the corresponding constraints alive.
The rename `Regions` to `LiveRegions` inside `RegionStore` is NFC change, that was done to make it clear, what is difference between regions stored in this two sets.

After ISEL, the "valid" loop header which has two predecessors
(one is preheader and the other one is latch) may be transformed
to have more than two predecessors by some optimizations, like tail
duplicator, if the old header's successor(will be changed to new
header) is a sub loop.
The predecessors of the new loop header are preheader, loop latch
and the loop latch(es) of the sub loop(old header's successor).
Before the patch, ctrloop pass assumes two predecessors for candidate
loop header. This patch fixes this case.

[clang-format] Do not parse certain characters in pragma directives
Currently, we parse lines inside of a compiler `#pragma` the same way we
parse any other line. This is fine for some cases, like separating
expressions and adding proper spacing, but in others it causes some poor
results from miscategorizing some tokens.
For example, the OpenMP offloading uses certain clauses that contain
special characters like `map(tofrom : A[0:N])`. This will be formatted
poorly as it will be split between lines on the first colon.
Additionally the subscript notation will lead to poor spacing. This can
be seen in the OpenMP tests as the automatic clang formatting with
inevitably ruin the formatting.
For example, the following contrived example will be formatted poorly.
```
#pragma omp target teams distribute collapse(2) map(to: A[0 : M * K]) \
map(to: B[0:K * N]) map(tofrom:C[0:M*N]) firstprivate(Alpha) \
firstprivate(Beta) firstprivate(X) firstprivate(D) firstprivate(Y) \
firstprivate(E) firstprivate(Z) firstprivate(F)
```
This results in this when formatted, which is far from ideal.
```
#pragma omp target teams distribute collapse(2) map(to \
: A [0:M * K]) \
map(to \
: B [0:K * N]) map(tofrom \
: C [0:M * N]) firstprivate(Alpha) \
firstprivate(Beta) firstprivate(X) firstprivate(D) firstprivate(Y) \
firstprivate(E) firstprivate(Z) firstprivate(F)
```
This patch seeks to improve this by adding extra logic where the parsing goes
awry. This is primarily caused by the colon being parsed as an inline-asm
directive and the brackes an objective-C expressions. Also the line gets
indented every single time the line is dropped.
This doesn't implement true parsing handling for OpenMP statements.

This implementation matches GCC behavior in that [[ https://eel.is/c++draft/temp.func.order#6.2.1 | temp.func.order p6.2.1 ]] is not implemented [1]. I reached out to the GCC author to confirm that some changes elsewhere to overload resolution are probably needed, but no solution has been developed sufficiently [3].
Most of the wordings are implemented straightforwardly. However,
for [[ https://eel.is/c++draft/temp.func.order#6.2.2 | temp.func.order p6.2.2 ]] "... or if the function parameters that positionally correspond between the two templates are not of the same type", the "same type" is not very clear ([2] is a bug related to this). Here is a quick example
```
template <C T, C U> int f(T, U);
template <typename T, C U> int f(U, T);
int x = f(0, 0);
```
Is the `U` and `T` from different `f`s the "same type"? The answer is NO even though both `U` and `T` are deduced to be `int` in this case. The reason is that `U` and `T` are dependent types, according to [[ https://eel.is/c++draft/temp.over.link#3 | temp.over.link p3 ]], they can not be the "same type".
To check if two function parameters are the "same type":
* For //function template//: compare the function parameter canonical types and return type between two function templates.
* For //class template/partial specialization//: by [[ https://eel.is/c++draft/temp.spec.partial.order#1.2 | temp.spec.partial.order p1.2 ]], compare the injected template arguments between two templates using hashing(TemplateArgument::Profile) is enough.

[flang] Restrict __float128 support for some build configurations.
This change is intended to resolve build issues reported in D134503.
A compiler supporting __float128 must define either __FLOAT128__ or
__SIZEOF_FLOAT128__ (or both). Additional check for _LIBCPP_VERSION
was added to disable __float128 for builds with libc++, because
__float128 support is incomplete there.
