Lightgbm: fix SWIG version -Wstrict-aliasing warnings
gcc produces huge number of warnings while compiling SWIG version now.
They should be fixed:
@guolinke
I think all these warning should be fixed, at least set some ignore tags in cmake.
Log can be found here: https://github.com/Microsoft/LightGBM/pull/1522#issuecomment-407361767
Also I think it'll good to set _lightgbm_swig as default target of make command when compiling with -DUSE_SWIG=ON flag, so that users will be able not to type make _lightgbm_swig, but just make.
@imatiach-msft Can you help please?

@StrikerRUS @guolinke sure, I can take a look. I've just looked at the thread you pointed to, I'm not sure I understand the full scope of the issue. Are the warnings generated only when SWIG is enabled? I assume yes. It looks like the warnings are only for the autogenerated .cxx file. Do you recommend that I try to disable them, or what would be the proper way to fix them in code? It looks like the same repeating issue:
"warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]"

@imatiach-msft Thank you for the prompt response!

Yes, only after
cmake -DUSE_SWIG=ON ..
make _lightgbm_swig
It looks like the same repeating issue:
"warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]"
Yeah, I've noticed this too! Only one repeating warning message.
BTW, Clang keeps silent, only gcc argues.
For better way to fix them ping @guolinke
UPD:
Have found full logs:
Clang (no warnings connected to SWIG): https://travis-ci.org/Microsoft/LightGBM/jobs/407412049

@StrikerRUS @imatiach-msft it seems there code are generated by swig.
https://github.com/Microsoft/LightGBM/blob/master/swig/lightgbmlib.i#L38-L45
I am not sure how to fix them in lightgbm side.

As it was discussed here https://github.com/Microsoft/LightGBM/pull/1599#issuecomment-416002682, there is actually no problem with building the default target. I was wrong in test setups.

OK, seems that the following is the key point:
- http://www.swig.org/Doc3.0/Java.html#Java_compiling_dynamic;
- http://www.swig.org/Doc3.0/Java.html#Java_typemaps_c_to_java_types
If you are going to use optimisations turned on with gcc (for example -O2), ensure you also compile with -fno-strict-aliasing. The GCC optimisations have become more aggressive from gcc-4.0 onwards and will result in code that fails with strict aliasing optimisations turned on.
Can the following be treated as a fix?
