[GSOC] LTO dump tool project

[Hrishikesh Kulkarni]

Hi,

I have created another branch lto-dump-tool-improved as suggested.
I have applied the patch for separation to lto-dump binary, made a few
necessary changes in other files and it is running successfully.
I will keep on adding previous work to this branch incrementally.

Please find the diff file attached for dumping of TREE statistics and
GIMPLE statistics.

for example:
(after configuring with --enable-gather-detailed-mem-stats)
-fdump-lto-gimple-stats will dump
GIMPLE statements
Kind                   Stmts      Bytes
---------------------------------------
assignments                0          0
phi nodes                  0          0
conditionals               0          0
everything else            0          0
---------------------------------------
Total                      0          0
---------------------------------------

-fdump-lto-tree-stats will dump
