Sometimes IC raises compilation errors when rebuild succeeds.
This happens because IC uses serialized decriptors
for non-dirty files. Serialized descriptors can be different
from source file descriptors. For example, a source file
may contain an implicit return type or an implicit visibility
for overridden methods, but serialized descriptors always
contain explicit return types & methods' visibilities.
These problems can be solved by expanding a scope of incremental compilation
just after the analysis, but before error reporting & code generation.
In other words, we need to compare descriptors before error reporting and code generation.
If there are new dirty files, current round of IC must be aborted,
next round must be performed with new dirty files.
