RFR: 8362559: [leyden] assert(!InstanceKlass::cast(receiver_klass)->is_not_initialized()) failed: receiver_klass must be initialized

[Vladimir Kozlov]

Fix is proposed by @iklam: add check that we precompiling AOT code in C1 where we check for initialized klass.

I renamed `is_compiled()` to `is_compile()` because we are in pricing of compiling.

Tested tier1-4,tier8-comp
