[COMMITTED 14/32] ada: Early freezeing of types with 'Size'Class

[Marc Poulhiès]

From: squirek <squi...@adacore.com>

This patch fixes an issue in the compiler whereby declarations of derived types
whose parent is a mutably tagged type cause early freezing of the parent type -
leading to spurious compile-time errors.

gcc/ada/ChangeLog:
        * sem_ch3.adb (Derived_Type_Declaration): Modify generation of
        compile time check.

Tested on x86_64-pc-linux-gnu, committed on master.
