[MLIR][OpenMP][SCF] Mark parallel regions as allocation scopes

MLIR has the notion of allocation scopes which specify that stack allocations (e.g. memref.alloca, llvm.alloca) should be freed or equivalently aren't available at the end of the corresponding region.
Currently neither OpenMP parallel nor SCF parallel regions have the notion of such a scope.

This clearly makes sense for an OpenMP parallel as this is implemented in with a new function which outlines the region, and clearly any allocations in that newly outlined function have a lifetime that ends at the return of the function, by definition.

While SCF.parallel doesn't have a guaranteed runtime which it is implemented with, this similarly makes sense for SCF.parallel since otherwise an allocation within an SCF.parallel will needlessly continue to allocate stack memory that isn't cleaned up until the function (or other allocation scope op) which contains the SCF.parallel returns. This means that it is impossible to represent thread or iteration-local memory without causing a stack blow-up. In the case that this stack-blow-up behavior is intended, this can be equivalently represented with an allocation outside of the SCF.parallel with a size equal to the number of iterations.

project-specific settings), this file can be used to customize an entire
lldb installation to a particular environment.

The feature is enabled at build time, by setting the
LLDB_GLOBAL_INIT_DIRECTORY variable to a path to a directory which
should contain an "lldbinit" file. Lldb will then load the file at
startup, if it exists, and if automatic init loading has not been
disabled. Relative paths will be resolved (at runtime) relative to the
location of the lldb library (liblldb or LLDB.framework).

The system-wide lldbinit file will be loaded first, before any
$HOME/.lldbinit and $CWD/.lldbinit files are processed, so that those
can override any system-wide settings.

[asan] Add support for disable_sanitizer_instrumentation attribute

For ASan this will effectively serve as a synonym for
__attribute__((no_sanitize("address"))).

Adding the disable_sanitizer_instrumentation to functions will drop the
sanitize_XXX attributes on the IR level.

This is the third reland of https://reviews.llvm.org/D114421.
Now that TSan test is fixed (https://reviews.llvm.org/D120050) there
should be no deadlocks.
