Replace a single dash with a double dash for options that have more than a single letter. llvm-bolt-wrapper.py has special treatment for output options such as "-o" and "-w" causing issues when a single dash is used, e.g. for "-write-dwp". The wrapper can be fixed as well, but using a double dash has other advantages as well. Reviewed By: rafauler Differential Revision: https://reviews.llvm.org/D127538
