  - [revert]SPVM::Hash->newa is rename to new, and original new is renamed to new_empty
    because SPVM::Hash->new(["foo" => SPVM::Int->new(4)]) is not good interface from Perl code.

      my $hash = SPVM::Hash->new;
      $hash->set_int(5);

  - fix INT32_MIN bugs
    In native function, -2147483648L is changed to -2147483648UL
0.0345 2018-06-12
  - Support precompile subroutine in distribution
    In this version, spvm subroutine can be precompiled before runtime.
    
    You can create precompiled shared library by the following command.
    
      perl -MSPVM::Build -e "SPVM::Build->new(build_dir => 'spvm_build')->create_shared_lib_precompile_dist('Point')";

  - remove len keyword and add scalar keyword
    SPVM don't have scalar context and list context, but Perl have them.
    In SPVM, you can get array by
    
      @$values
    
    syntax. but this confuse you sometime
    because
    
      foo(@$values);
    
    is seem list expansion. This is always array length in SPVM.
    Until now I provided len keyword , but this is not Perlish syntax.
    From now I provide scalar keyword and another array syntax.
      
      scalar @$values
    
    You can write the following subroutine call
    
      foo(scalar @$values);
  - add SPVM_NATIVE_SUB macro to spvm_native, and SPVM native function defenition way is changed to the following
      
      // My::Example::sin
      int32_t SPVM_NATIVE_SUB(My__Example__sin) (SPVM_ENV* env, SPVM_VALUE* args) {
        (void)env;
        
        double value = sin(args[0].dval);
        
        args[0].dval = value;
        
        return 0;
      }
    
    SPVM_NATIVE_SUB macro automatically expand function name to SPVM_NATIVE_My__Example__sin.
    This is very simple way to define native function.
    Newbie only learn SPVM_NATIVE_SUB macro and replace package name : to _ and join package name and subroutine name with __.
