Max Moroz 7d614bdaf0 [llvm-cov] Multi-threaded implementation of prepareFileReports method.
Summary:
Local testing has demonstrated a great speed improvement, compare the following:

1) Existing version:
```
$ time llvm-cov show -format=html -output-dir=report -instr-profile=... ...
The tool has been launched:                            00:00:00
Loading coverage data:                                 00:00:00
Get unique source files:                               00:00:33
Creating an index out of the source files:             00:00:34
Going into prepareFileReports:                         00:00:34
Going to emit summary information for each file:       00:28:55 <-- 28:21 min!
Going to emit links to files with no function:         00:28:55
Launching 32 threads for generating HTML files:        00:28:55

real  37m43.651s
user  112m5.540s
sys   7m39.872s
```

2) Multi-threaded version with 32 CPUs:
```
$ time llvm-cov show -format=html -output-dir=report -instr-profile=... ...
The tool has been launched:                            00:00:00
Loading coverage data:                                 00:00:00
Get unique source files:                               00:00:38
Creating an index out of the source files:             00:00:40
Going into prepareFileReports:                         00:00:40
Preparing file reports using 32 threads:               00:00:40
# Creating thread tasks for the following number of files: 16422
Going to emit summary information for each file:       00:01:57 <-- 1:17 min!
Going to emit links to files with no function:         00:01:58
Launching 32 threads for generating HTML files:        00:01:58

real  11m2.044s
user  134m48.124s
sys   7m53.388s
```
