lang/lua55: Add port: Powerful, efficient, lightweight, embeddable scripting language (Version 5.5)
Lua is a programming language originally designed for extending applications,
but also frequently used as a general-purpose, stand-alone language. Lua
combines simple procedural syntax (similar to Pascal) with powerful data
description constructs based on associative arrays and extensible semantics.
Lua is dynamically typed, interpreted from bytecodes, and has automatic memory
management with garbage collection, making it ideal for configuration,
scripting, and rapid prototyping.
A fundamental concept in the design of Lua is to provide meta-mechanisms for
implementing features, instead of providing a host of features directly in
the language. For example, although Lua is not a pure object-oriented
language, it does provide meta-mechanisms for implementing classes and
inheritance. Lua's meta-mechanisms bring an economy of concepts and keep the
language small, while allowing the semantics to be extended in unconventional
ways. Extensible semantics is a distinguishing feature of Lua.
Lua is implemented as a small library of C functions, written in ANSI C, and

[IR] Fix !invariant.group in combineMetadataForCSE when K moves (#200551)
SimplifyCFG mergeConditionalStoreToAddress currently transforms
if (cond)
store ptr, x !invariant.group;
else
store ptr, y;
into
store ptr, select(cond, x, y) !invariant.group; // BUG
It's clearly not valid to preserve !invariant.group here.
Fix this inside combineMetadataForCSE. It can only preserve
!invariant.group if
1. !DoesKMove, meaning that original instruction ("K") is replaced by

[asan] NFC: clang-format allocator-related files (#200478)
Depends on #200615
Groundwork for #196413.
Mechanical cleanup of allocator related files in preparation of
functional changes. clang-format (v21.1.2) applied whole-file to:
compiler-rt/lib/asan/asan_allocator.cpp
compiler-rt/lib/asan/asan_allocator.h
compiler-rt/lib/asan/asan_malloc_linux.cpp
compiler-rt/lib/asan/asan_malloc_mac.cpp
compiler-rt/lib/asan/asan_new_delete.cpp
compiler-rt/lib/asan/tests/asan_noinst_test.cpp
Both compiler-rt/lib/asan/.clang-format and
compiler-rt/lib/sanitizer_common/.clang-format use
"BasedOnStyle: Google", so pointer alignment becomes "Type* name"
throughout.

[asan] NFC: tag ambiguous literal args at Allocate call sites (#200615)
Groundwork for #200478
Add /*name=*/ comments to ambiguous literal call-site arguments in
compiler-rt/lib/asan/asan_allocator.cpp so the parameter name is visible
at the call site for the Allocate / instance.Allocate uses. Covers the
can_fill flag and the bare alignment literals (8, 16, 0) used by:
asan_malloc / asan_vec_malloc / asan_realloc / asan_valloc /
asan_pvalloc / asan_memalign / asan_aligned_alloc /
asan_posix_memalign / asan_new / asan_new_aligned
and the internal Reallocate / Calloc paths.
NFC.
