Because SerializationJvmIrIntrinsicSupport does not instantiate annotations yet,
this info could be lost. As a workaround, it is possible to call Companion.serializer()
functions instead of direct serializer instantiation, as they are plugin-generated
and correctly handle annotations.
Note that for some cases (enums & interfaces) this WA is not enough, so additional work
is needed later.
Fixes https://github.com/Kotlin/kotlinx.serialization/issues/2179
instead, plugins should emit the code similar to the TYPE_OF one with
a special call to MagicApiIntrinsics.voidMagicApiCall directly afterwards.
This is required because old compiler need to correctly inline code
rewritten by plugin.
Add intrinsic for kotlinx.serialization.serializer<T>() function.
Plugin intrinsic for old backend is removed because it is too hard
and unjustifiable to unify them.
(Old is created first because all intrinsics emit bytecode anyway)
Provide intrinsic for serializer<T>() function so it won't
invoke typeOf() construction and KType->KSerializer conversion
making it fast and truly reflectionless
Add support for recalculating stack size in plugin-defined intrinsics
since it is needed for correct work:
Unify method for recalculating stack size with existing typeOf intrinsic
Add testdata for IR for future intrinsic in IR
