Maksim Panchenko 489e514530 [BOLT] Improve annotations format and processing 
Summary:
Change the way annotations are stored and processed.

Embed annotation type/index into immediate value stored as an operand.
This limits the effective range of values that could be stored as
annotations to 56 bits, which is still plenty for most integer types
that we use and for pointers on real systems. High 8 bits are reserved
for storing annotation type/index.

Expand the interface for general annotations to include reference to
annotations by index. The main purpose of this interface is to improve
performance of annotations that are used by heavy (>O(N)) algorithms,
such as data flow analysis.

For -frame-opt pass, new memory usage and processing times are slightly
better compared to those before refactoring.
