Convert the non-fixed-point side to a fixed-point type before doing the
comparison.

d9b377d8b1 [clang][bytecode] Don't produce a null type when checking new exprs (#110252) 
getType() might give us the right type already, so use that instead of
calling getPointeeType() for all CXXNewExprs.

3ea55d3cb0 [clang][bytecode] Add a source location to destructor calls (#110121) 
The added test case is still diagnosed differently, but I'm not sure
which version is better.

f3111cc77b [clang][bytecode][NFC] Remove a useless cast 
getDecl() now always returns a ValueDecl.

a024a0ceed [clang][bytecode] Override InConstantContext flag for immediate calls (#109967) 
And fix the diagnostics for __builtin_is_constant_evaluated(). We can be
in a non-constant context, but calling an immediate function always
makes the context constant for the duration of that call.

1cdcec5884 [clang][bytecode] Handle vector comma op (#109827) 
Currently we were not handle comma op for vector operands, after this
patch, we handle the comma op for vector operands with common way.

4bd3a62cd6 [clang][bytecode] Fix diagnosing std::construct_at with wrong type (#109828) 
We can't make the assumption that types are always fine in std
functions.

e1365ce222 [clang][bytecode][NFC] Add type assertions to ArrayElem{,Pop} (#109829)

679c9717df [clang][bytecode] Fix vector shifts on big-endian systems (#109800) 
For shifts, the LHS and RHS element types might be different. The
variable naming here could probably use some love now, but I'm trying to
fix this as fast as possible.

c712ab829b [clang][bytecode] Implement placement-new (#107033) 
If we have a placement-new destination already, use that instead of
allocating a new one.
Tests are partially based on
`test/SemaCXX/cxx2c-constexpr-placement-new.cpp`.

f86050de73 [clang][bytecode] Don't call checkLiteralType() in visitInitializer() (#109530) 
We were calling checkLiteralType() too many time and rejecting some
things we shouldn't. Add The calls manually when handling
MaterializeTemporaryExprs. Maybe we should call it in other places as
well, but adding more calls is easier than removing them from a generic
code path.

compound assignment operator.
