a2639798a8 llvm-cov: Added -b option for branch probabilities.
This option tells llvm-cov to print out branch probabilities when
a basic block contains multiple branches. It also prints out some
function summary info including the number of times the function enters,
the percent of time it returns, and how many blocks were executed.

Also updated tests.

30d5ef51e4 llvm-cov: Added -a option for block data.
Similar to gcov, llvm-cov will now print out the block count at the end
of each block. Multiple blocks can end on the same line.

One computational difference is by using -a, llvm-cov will no longer
simply add the block counts together to form a line count. Instead, it
will take the maximum of the block counts on that line. This has a
similar effect to what gcov does, but generates more correct counts in
certain scenarios.

Also updated tests.

5004f51a33 Copy input files to test directory.
With r196184, llvm-cov creates a new file right next to the input file.
However, the Inputs-directory can't simply be assumed to be writable
under all build systems.

Also, this prevents a new source file from showing up in the source tree
if the test aborts before the call to "rm".

6cd7a3fa79 llvm-cov: Removed output to STDOUT/specified file.
Instead of asking the user to specify a single file to output coverage
info and defaulting to STDOUT, llvm-cov now creates files for each
source file with a naming system of: <source filename> + ".llcov".

This is what gcov does and although it can clutter the working directory
with numerous coverage files, it will be easier to hook the llvm-cov
output to tools which operate on this assumption (such as lcov).

d23c759c0f llvm-cov: Added file checksum to gcno and gcda files.
Instead of permanently outputting "MVLL" as the file checksum, clang
will create gcno and gcda checksums by hashing the destination block
numbers of every arc. This allows for llvm-cov to check if the two gcov
files are synchronized.

Regenerated the test files so they contain the checksum. Also added
negative test to ensure error when the checksums don't match.

131a764e0e llvm-cov: Removed StringMap holding GCOVLines.
According to the hazy gcov documentation, it appeared to be technically
possible for lines within a block to belong to different source files.
However, upon further investigation, gcov does not actually support
multiple source files for a single block.

This change removes a level of separation between blocks and lines by
replacing the StringMap of GCOVLines with a SmallVector of ints
representing line numbers. This also means that the GCOVLines class is
no longer needed.

This paves the way for supporting the "-a" option, which will output
block information.

dbb51ff01f llvm-cov: Replaced asserts with proper error handling.
Unified the interface for read functions. They all return a boolean
indicating if the read from file succeeded. Functions that previously
returned the read value now store it into a variable that is passed in
by reference instead. Callers will need to check the return value to
detect if an error occurred.

Also added a new test which ensures that no assertions occur when file
contains invalid data. llvm-cov should return with error code 1 upon
failure.

0cbecb56fb Revert "Added basic unit test for llvm-cov."
This reverts commit r194451.

Not sure why the tests are failing on the buildbot. They run fine on my
local machine. Could it possibly be because of the endianness of the
architectures? The GCNO and GCDA files are little-endian encoded, and
llvm-cov expects it to remain that way. Is this a safe assumption?

0c873adc82 llvm-objdump: Dump COFF import table if -private-headers option is given.
This is a patch to add capability to llvm-objdump to dump COFF Import Table
entries, so that we can write tests for LLD checking Import Table contents.

llvm-objdump did not print anything but just file name if the format is COFF
and -private-headers option is given. This is a patch adds capability for
dumping DLL Import Table, which is specific to the COFF format.

In this patch I defined a new iterator to iterate over import table entries.
Also added a few functions to COFFObjectFile.cpp to access fields of the entry.

24ec2e5a72 [tests] Cleanup initialization of test suffixes.
- Instead of setting the suffixes in a bunch of places, just set one master
   list in the top-level config. We now only modify the suffix list in a few
   suites that have one particular unique suffix (.ml, .mc, .yaml, .td, .py).

 - Aside from removing the need for a bunch of lit.local.cfg files, this enables
   4 tests that were inadvertently being skipped (one in
   Transforms/BranchFolding, a .s file each in DebugInfo/AArch64 and
   CodeGen/PowerPC, and one in CodeGen/SI which is now failing and has been
   XFAILED).

 - This commit also fixes a bunch of config files to use config.root instead of
   older copy-pasted code.
