[lldb][CPlusPlus] Add abi_tag support to the CPlusPlusNameParser
This patch teaches the `CPlusPlusNameParser` to parse the
demangled/prettified [[gnu::abi_tag(...)]] attribute. The demangled format
isn't standardized and the additions to the parser were mainly driven
using Clang (and the limited information on this from the official
Clang docs).
This change is motivated by multiple failures around step-in
behaviour for libcxx APIs (many of which have ABI tags as of recently).
LLDB determines whether the `step-avoid-regexp` matches the current
frame by parsing the scope-qualified name out of the demangled
function symbol. On failure, the `CPlusPlusNameParser` will simply
return the fully demangled name (which can include the return type)
to the caller, which in `FrameMatchesAvoidCriteria` means we will
not correctly decide whether we should stop at a frame or not if
the function has an abi_tag.
Ideally we wouldn't want to rely on the non-standard format
of demangled attributes. Alternatives would be:
1. Use the mangle tree API to do the parsing for us
2. Reconstruct the scope-qualified name from DWARF instead of parsing
the demangled name
(1) isn't feasible without a significant refactor of `lldb_private::Mangled`,
if we want to do this efficiently.
(2) could be feasible in cases where debug-info for a frame is
available. But it does mean we certain operations (such as step-in regexp,
and frame function names) won't work with/won't show ABI tags.
**Testing**
* Un-XFAILed step-in API test
* Added parser unit-tests

[libc++] type_traits: fix short-circuiting in std::conjunction.
Replace the two-level implementation with a simpler one that directly subclasses
the predicates, avoiding the instantiation of the template to get the `type`
member in a situation where we should short-circuit. This prevents incorrect
diagnostics when the instantiated predicate contains a static assertion.
Add a test case that reproduced the previous problem. The existing test case
involving `HasNoValue` didn't catch the problem because `HasNoValue` was in the
final position. The bug comes up when the predicate that shouldn't be
instantiated is after the short-circuit position but there is more to follow,
because then `__conjunction_impl<False, BadPredicate, ...>` instantiates
`__conjunction_impl<BadPredicate, ...>` (in order to obtain its `type` member),
which in turn instantiates `BadPredicate` in order to obtain its `value` member.
In contrast the new implementation doesn't recurse in instantiation any further
than it needs to, because it doesn't require particular members of the recursive
case.
I've also updated the test cases for `std::disjunction` to match,
although it doesn't have the same particular bug (its implementation is
quite different).

[Arm64EC] Refer to dllimport'ed functions correctly.
Arm64EC has two different ways to refer to dllimport'ed functions in an
object file. One is using the usual __imp_ prefix, the other is using an
Arm64EC-specific prefix __imp_aux_. As far as I can tell, if a function
is in an x64 DLL, __imp_aux_ refers to the actual x64 address, while
__imp_ points to some linker-generated code that calls the exit thunk.
So __imp_aux_ is used to refer to the address in non-call contexts,
while __imp_ is used for calls to avoid the indirect call checker.
There's one twist to this, though: if an object refers to a symbol using
the __imp_aux_ prefix, the object file's symbol table must also contain
the symbol with the usual __imp_ prefix. The symbol doesn't actually
have to be used anywhere, it just has to exist; otherwise, the linker's
symbol lookup in x64 import libraries doesn't work correctly. Currently,
this is handled by emitting a .globl __imp_foo directive; we could try
to design some better way to handle this.
One minor quirk I haven't figured out: apparently, in Arm64EC mode, MSVC
prefers to use a linker-synthesized stub to call dllimport'ed functions,
instead of branching directly. The linker stub appears to do the same
thing that inline code would do, so not sure if it's just a code-size
optimization, or if the synthesized stub can actually do something other
than just load from the import table in some circumstances.
