Reland "[compiler-rt][test] Heed COMPILER_RT_DEBUG when compiling unittests"
When trying to debug some `compiler-rt` unittests, I initially had a hard
time because
- even in a `Debug` build one needs to set `COMPILER_RT_DEBUG` to get
debugging info for some of the code and
- even so the unittests used a hardcoded `-O2` which often makes debugging
impossible.
This patch addresses this by instead using `-O0` if `COMPILER_RT_DEBUG`.
Changes relative to the previous commit:
- Use `string(APPEND)` for `COMPILER_RT_TEST_COMPILER_CFLAGS`.
- Omit `-O3` from `COMPILER_RT_TEST_COMPILER_CFLAGS` in non-debug builds for now.
- Provide `__sanitizer::integral_constant<bool, true>::value` instantiation
for `sanitizer_type_traits_test.cpp` in debug builds.
- Disable subtests of `tsan/tests/unit/tsan_trace_test.cpp` that deadlock
in debug builds.
- `XFAIL` `tsan/Linux/check_memcpy.c` in debug builds.

Implement CWG2631
Implement https://cplusplus.github.io/CWG/issues/2631.html.
Immediate calls in default arguments and defaults members
are not evaluated.
Instead, we evaluate them when constructing a
`CXXDefaultArgExpr`/`BuildCXXDefaultInitExpr`.
The immediate calls are executed by doing a
transform on the initializing expression.
Note that lambdas are not considering subexpressions so
we do not need to transform them.
As a result of this patch, unused default member
initializers are not considered odr-used, and
errors about members binding to local variables
in an outer scope only surface at the point
where a constructor is defined.

[LoongArch] Add custom parser for atomic instructions' memory operand
In order to be compatible with the form of the atomic instruction in
GAS that accepts the fourth operand as 0 (i.e. `am* $rd, $rk, $rj, 0`),
we need to treat `$rj, 0` as one operand, but only print `$rj`.
For this, the number of result operands of inline assembly memory
operand `ZB` constraint is modified to 2 (reg + 0).
Restrictions on register usage in `am*` instructions have also been
adjusted. When `$rd` is equal to `$r0`, the instruction must be
considered legal, because of some special usage like `PseudoUNIMP`.

These were trying to check if there was not an llvm.objc call before a

function. Really this was matching the closing } in "bitcast {}* %self
to i8*", which can't be what anyone intended. This broke after
converting the test to opaque pointer deleted this bitcast.
There are in fact @llvm.obj calls remaining in the function, so this
may indicate the transform this was intended to check is actually
broken. In @"\01-[A z]" (great test name), the first retain call seems
to move down to the printf. The second case, @"\01-[Top0 _getX]", has
no change.
Change the checks to what's produced and add FIXMES. Also change the }
checks to match only at the start of the line for the function end.
