Allow to specify loop-unrolling with optional parameters explicitly
spelled out in -passes pipeline specification.
Introducing somewhat generic way of specifying parameters parsing via
FUNCTION_PASS_PARAMETRIZED pass registration.
Syntax of parametrized unroll pass name is as follows:
'unroll<' parameter-list '>'
Where parameter-list is ';'-separate list of parameter names and optlevel
optlevel: 'O[0-3]'
parameter: { 'partial' | 'peeling' | 'runtime' | 'upperbound' }
negated: 'no-' parameter
Example:
-passes=loop(unroll<O3;runtime;no-upperbound>)
this invokes LoopUnrollPass configured with OptLevel=3,
Runtime, no UpperBound, everything else by default.
