Add bytes accessed to HLO profile output. Bytes accessed is a measure of the bytes read/written from memory during execution of an HLO op. It is typically the sum of the sizes of the operands and output. Sample line from profile table:
337 cycles ( 47.87%) :: 0.5 usec @ f_nom :: 263.80MFLOP/s :: 12.0KiB :: %multiply = ...
The 12.0KiB is the change.
As part of this change unconditionally gather bytes accessed information with HloCostAnalysis. This requires that the shape size computation be universally accessible so ShapeSizeBytes method was added to xla::Compiler which enabled some cleanup in various places.
