The loop in findNextSetBit() runs one pass more than it should.
On 64-bit architectures this does not cause a problem, but 32-bit
architectures mask the shift count to 5 bits which limits the number of
shifts inside a range of 0 to 31. Shifting by 32 has the same effect as
shifting by 0, so if the first bit in the set is 1, the function will return
with Index different from EndIndexVal. Because of that, range-based for
loops iterating thorough architectures will continue until hitting a 0 in
the set, resulting in n additional iterations, where n is equal to the
number of consecutive 1 bits at the start the set.
Ultimately TBDv1.WriteFile and TBDv2.WriteFile will output additional
architectures causing a failure in the unit tests.
Patch by Milos Stojanovic.

Summary: This changes the Architecture enum to use a prefix (AK_) to prevent the
preprocessor from replacing i386 with 1 when building llvm/clang for i386.

Add basic infrastructure for reading and writting TBD files (version 1 - 3).
The TextAPI library is not used by anything yet (besides the unit tests). Tool
support will be added in a separate commit.
The TBD format is currently documented in the implementation file (TextStub.cpp).

Update: This contains changes to fix issues discovered by the bots:
- add parentheses to silence warnings.
- rename variables
- use PlatformType from BinaryFormat
- Trying if switching from a vector to an array will appeas the bots.
- Replace the tuple with a struct to work around an explicit constructor bug.
- This fixes an issue where we were leaking the YAML document if there was a
parsing error.
Updated the license information in all files.

Moving to PlatformType from BinaryFormat had some UB fallout when handing
unknown platforms or malformed input files.
This should fix the sanitizer bots.
