[clang][bytecode] Add support for typeid pointers ( #121251 )
...
Add it as another kind of pointer, saving both a `Type*` for the result
of the typeid() expression as well as one for the type of the typeid
expression.

We still need to check the input pointer, so let this go through
BitCastPrim.

[clang][bytecode] Start implementing __builtin_bit_cast ( #112126 )
...
This is a subset of #68288 , with hopefully narrower scope. It does not
support bitcasting to non-integral types yet.
Bitfields are supported, but only if they result in a full byte-sized
final buffer. It does not support casting from null-pointers yet or
casting from indeterminate bits.
The tests are from #68288 and partially from #74775 .
The `BitcastBuffer` struct is currently always working in single bits,
but I plan to (try to) optimize this for the common full-byte case.

[clang][bytecode] Diagnose invalid declrefs differently if we've... ( #113140 )

... tried their initializer already. In that case, diagnose the
non-const initializer instead of the reference to a non-constexpr
variable later. This is used in a lot of openmp tests.

[clang][bytecode] Check for memory leaks after destroying global scope ( #112868 )
...
The global scope we create when evaluating expressions might free some
of the dynamic memory allocations, so we can't check for memory leaks
before destroying it.
