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.

Fix BOLT's constant island mapping when a constant island marked by $d
spans multiple functions. Currently, because BOLT only marks the
constant island in the first function where $d is located, if the next
function contains data at its start, BOLT will miss the data and try
to disassemble it. This patch adds code to explicitly go through all
symbols between $d and $x markers and mark their respective offsets as
data, which stops BOLT from trying to disassemble data. It also adds
MarkerType enum and refactors related functions.
