Fixed recompiler error when the cpp filename is too long

[roby65]

Fixes errors like:

Failed to open file for writing: ./output/Insert__H1ZPC22AptFileSavedInputState_Q32EA6Stringt11BasicString2Zt22StringAsVectorEncoding1Z22AptFileSavedInputStateZ20StringAsVectorPolicyRCX00T1RCQ42EA6Stringt11BasicString2Zt22StringAsVectorEncoding1Z22AptFileSavedInputStateZ20StringAsVectorPolicy11DbgIterator_v_0x3d0768.cpp

Now filename is truncated to a max of 100 characters, like this:

Insert__H1ZPC22AptFileSavedInputState_Q32EA6Stringt11BasicString2Zt22StringAsVectorEnco_0x3d0768.cpp

I decided 100 as max filename length, with 200 characters I was getting unspecified compiler errors. Under 100 characters looks like the sweet spot.
