Fixed llvm-cov to count edges instead of blocks.
This was a fundamental flaw in llvm-cov where it treated the values in

incorrect line counts when branching was present. Instead, the edge
counts should be summed to obtain the correct block count.
The fix was tested using custom test files as well as single source
files from the test-suite directory. The behaviour can be verified by
reading the GCOV documentation that describes the GCDA spec ("ARC_COUNTS
gives the counter values for those arcs that are instrumented") and the
header description provided by GCOVProfiling.cpp ("instruments the code
that runs to records (sic) the edges between blocks that run and emit a
complementary "gcda" file on exit").

Calling _chkstk is required on ELF as well as COFF on Windows. Without
_chkstk, functions requiring large stack crash in initialization code.
Previous code tested for COFF format but not Mach-O and this patch modifies
the code to test for Windows OS (both Windows target and MingW target)
but not Mach-O object format: Looks like macho environment was used to
build some EFI code.

Use a map instead of vector to store line counts.
There are a few motivations for this:
- Using a map allows for checking if line is in map. This differentiates
unexecutable lines (such as comments) from unexecuted logical lines of
code. "#####" is now outputted in this case, in line with gcov.
- Source files are no longer read in twice: once when storing the line
counts, and once when outputting the data.
- Greatly simplifies the function FileInfo::addLineCount().
