Add tuning debug builds for debugger

Browse Source 
Summary:
A new variable has been added to CMakeLists -- `PREFERRED_DEBUGGER`.
Here, you can specify which debugger you are using, so that the compiler
produces tuned debug builds for that debugger. Currently only 'gdb' and
'lldb' are supported, since we  use 'gcc' and 'clang' compilers.
Unsupported combination of `PREFERRED_DEBUGGER` and used compiler is
displayed as a warning, and the build uses default debug flags.
