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.

Summary:
Since gcc/ld could produce and expect PIE files we need to pass -no-pie option to avoid linking errors for tests.

Summary:
Fix issue with splitting critical edges originating at
the same BB in ShrinkWrapping::splitFrontierCritEdges.
Splitting of critical edges originating at the same FromBB
wasn't handled correctly as the Frontier at index corresponding
to FromBB was overwritten with basic blocks created for
multiple DestinationBBs.
