Maksim Panchenko d648aa1b8e [BOLT][TEST] Use double dash flags in tests
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.

Maksim Panchenko cbf530bf41 [BOLT] Add pass to normalize CFG
Summary:
Some optimizations may remove all instructions in a basic block.

The pass will cleanup the CFG afterwards by removing empty basic
blocks and merging duplicate CFG edges.

The normalized CFG is printed under '-print-normalized' option.

Amir Ayupov 8331f75e28 [BOLT][TEST] Rename tests to follow standard naming scheme
Summary:
The majority of tests in LLVM projects are using - instead of _ in the name,
i.e. `check-something.test` is preferred over `check_something.test`.

It makes sense for us to adopt the same naming scheme for our future tests and
to rename existing ones.
