"[Program Block Range]" indicates the range of program basic block

otherwise it prints the symbol+offset instead.
v4:
---
Use source lines or symbol+offset to indicate the basic block. It should
be easier to understand.
v3:
---
Cast 'struct hist_entry' to 'struct block_hist' in hist_entry__block_fprintf.
Use symbol_conf.report_block to check if executing hist_entry__block_fprintf.
v2:
---
Keep standard perf diff format and display the 'Baseline' and
'Shared Object'.
The output is sorted by "Baseline" and the basic blocks in the same
function are sorted by cycles diff.

Cast 'struct hist_entry' to 'struct block_hist' in hist_entry__block_fprintf.
Use symbol_conf.report_block to check if executing hist_entry__block_fprintf.
v2:
---
Keep standard perf diff format and display the 'Baseline' and
'Shared Object'.
The output is sorted by "Baseline" and the basic blocks in the same
function are sorted by cycles diff.

"[Program Block Range]" indicates the range of program basic block
(start -> end). If we can find the source line it prints the source line
otherwise it prints the symbol+offset instead.
v4:
---
Use source lines or symbol+offset to indicate the basic block. It should
be easier to understand.
v3:
---
Cast 'struct hist_entry' to 'struct block_hist' in hist_entry__block_fprintf.
Use symbol_conf.report_block to check if executing hist_entry__block_fprintf.
v2:
---
Keep standard perf diff format and display the 'Baseline' and
'Shared Object'.
The output is sorted by "Baseline" and the basic blocks in the same
function are sorted by cycles diff.
