Optimization of beams string table generation

[Paul Guyot]

Hello,

beam_dict:string and the whole string table code is based on naive string search and compiling a module with thousands of binary strings takes several minutes. The following patch replaces the code with calls to binary:match/2.

git fetch git://github.com/pguyot/otp.git pg/optimize_beam_dict_string_table

http://github.com/pguyot/otp/commit/13ca6aa7b74c7887ae6c3a42b35769524af4903a

Regards,

Paul
