Most of the dependencies cleaned up here look like copy/paste errors when creating

* Unnecessary hard coding of constant operations in matchers

Fix bugs in GPUToNVVM lowering
The current lowering from GPU to NVVM does
not correctly handle the following cases when
lowering the gpu shuffle op.
1. When the active width is set to 32 (all lanes),
then the current approach computes (1 << 32) -1 which
results in poison values in the LLVM IR. We fix this by
defining the active mask as (-1) >> (32 - width).
2. In the case of shuffle up, the computation of the third
operand c has to be different from the other 3 modes due to
the op definition in the ISA reference.
(https://docs.nvidia.com/cuda/parallel-thread-execution/index.html)
Specifically, the predicate value is computed as j >= maxLane
for up and j <= maxLane for all other modes. We fix this by
computing maskAndClamp as 32 - width for this mode.
TEST: We modify the existing test and add more checks for the up mode.

[libc++] Make sure basic_string::reserve(n) never shrinks in all Standard modes
Since basic_string::reserve(n) is instantiated in the shared library but also
available to the compiler for inlining, its definition should not depend on
things like the Standard mode in use. Indeed, that flag may not match between
how the shared library is compiled and how users are compiling their own code,
resulting in ODR violations.
However, note that we retain the behavior of basic_string::reserve() to
shrink the string for backwards compatibility reasons. While it would
technically be conforming to not shrink, we believe user expectation is
for it to shrink, and so existing code might have been written based on
that assumption. We prefer to not break such code, even though that makes
basic_string::reserve() and basic_string::reserve(0) not equivalent anymore.

[lldb/Plugins] Fix ScriptedThread IndexID reporting
When listing all the Scripted Threads of a ScriptedProcess, we can see that all
have the thread index set to 1. This is caused by the lldb_private::Thread
constructor, which sets the m_index_id member using the provided thread id `tid`.
Because the call to the super constructor is done before instantiating
the `ScriptedThreadInterface`, lldb can't fetch the thread id from the
script instance, so it uses `LLDB_INVALID_THREAD_ID` instead.
To mitigate this, this patch takes advantage of the `ScriptedThread::Create`
fallible constructor idiom to defer calling the `ScriptedThread` constructor
(and the `Thread` super constructor with it), until we can fetch a valid
thread id `tid` from the `ScriptedThreadInterface`.

This patch adds support of multiple Scripted Threads in a ScriptedProcess.
This is done by fetching the Scripted Threads info dictionary at every

already available.
This patch also adds the ability to pass a pointer of a script interpreter

the script object initializer in the ScriptedInterface constructor.
This is used to instantiate the ScriptedThreadInterface from the
ScriptedThread constructor, to be able to perform call on that script
interpreter object instance.
