[clang-tidy] new check: bugprone-too-small-loop-variable
The new checker searches for those for loops which has a loop variable with a "too small" type which means this type can't represent all values which are part of the iteration range.
For example:
```
int main() {
long size = 300000;
for( short int i = 0; i < size; ++i) {}
}
```
The short type leads to infinite loop here because it can't store all values in the `[0..size]` interval. In a real use case, size means a container's size which depends on the user input. Which means for small amount of objects the algorithm works, but with a larger user input the software will freeze.
The idea of the checker comes from the LibreOffice project, where the same check was implemented as a clang compiler plugin, called `LoopVarTooSmall` (LLVM licensed).
The idea is the same behind this check, but the code is different because of the different framework.

This change allows to run clang-based tools, like clang-tidy or clangd,

On MacOS clang can find the C++ standard library relative to the
compiler installation dir.
The logic to do this was based on resource dir as an approximation of
where the compiler is installed. This broke the tools that read
'compile_commands.json' and don't ship with the compiler, as they
typically change resource dir.
To workaround this, we now use compiler install dir detected by the driver
to better mimic the behavior of the original compiler when replaying the

[llvm-mca] Correctly update the resource strategy for processor resources with multiple units.
When looking at the tests committed by Roman at r346587, I noticed that numbers

In particular, according to the aut-generated CHECK lines in tests
memcpy-like-test.s and store-throughput.s, resource pressure for PdAGU01
was not uniformly distributed among the two AGEN pipes.
It turns out that the reason why pressure was not correctly distributed, was
because the "resource selection strategy" object associated with PdAGU01 was not
correctly updated on the event of AGEN pipe used.
As a result, llvm-mca was not simulating a round-robin pipeline allocation for
PdAGU01. Instead, PdAGU1 was always prioritized over PdAGU0.

resources declaring multiple units, are correctly notified in the event of

[GCOV] Add options to filter files which must be instrumented.
Summary:
When making code coverage, a lot of files (like the ones coming from /usr/include) are removed when post-processing gcno/gcda so finally they doen't need to be instrumented nor to appear in gcno/gcda.
The goal of the patch is to be able to filter the files we want to instrument, there are several advantages to do that:
- improve speed (no overhead due to instrumentation on files we don't care)
- reduce gcno/gcda size
- it gives the possibility to easily instrument only few files (e.g. ones modified in a patch) without changing the build system
- need to accept this patch to be enabled in clang: https://reviews.llvm.org/D52034

Class with no user-defined destructor that has an inherited member that has a
non-trivial destructor and a non-default constructor will attempt to emit a
destructor despite being marked as __attribute((no_destroy)) in which case it
would trigger an assertion due to an incorrect assumption.
In addition this adds missing test coverage for IR generation for no_destroy.

[GCRoot] Remove some unneccessary complexity
The GCStrategy provides three configuration options were are largely redundant.
1) Support for conditionally lowering gcread and gcwrite to loads and stores. This is redundant since any GC which wished to use these abstractions would lower them out of existance before the built in lowering anyways. As such, there's no need to have the lowering being conditional.
2) Conditional initialization for allocas marked via gcroot. Semantically, roots have to be initialized before first potential use. Arguably, the frontend really should have responsibility for that, but the old API allowed the frontend to ignore this detail. Only one builtin GC used the non-initializing mode. Since no one to my knowledge actually uses the ErlangGC strategy, I decide the slight pessimization was worth the simplicity. If that turns out to be problematic, we can always improve the insertion algorithm to detect more existing initializing stores.

FunctionDecl::Create() takes as its T parameter the type of function

looks to have been copypasta'd around a bit, but the number of correct

the same and fixing up the call sites instead.
