The test exercises an implicit ptr-to-int conversion which is made an error in
D129881. We acknowledge the error but still want to test this case.
Add `-Wno-int-conversion` to silence the error.

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.
