scalar op when scalar ops are performed using a subset (typically, the
first lane) of the vector register file.

[TextAPI] Fix off-by-one error in the bit index extraction loop

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.

Summary:
Strings in minidump files are stored as a 32-bit length field, giving
the length of the string in *bytes*, which is followed by the
appropriate number of UTF16 code units. The string is also supposed to
be null-terminated, and the null-terminator is not a part of the length
field. This patch:
- adds support for reading these strings out of the minidump file (this
  implementation does not depend on proper null-termination)
- adds support for writing them to a minidump file
- using the previous two pieces implements proper (de)serialization of
  the CSDVersion field of the SystemInfo stream. Previously, this was
  only read/written as hex, and no attempt was made to access the
  referenced string -- now this string is read and written correctly.

The changes are tested via yaml2obj|obj2yaml round-trip as well as a
unit test which checks the corner cases of the string deserialization
logic.

[FastISel] Fix the crash in gc.result lowering

The Fast ISel has a fallback to SelectionDAGISel in case it cannot handle the instruction.
This works as follows:
Using reverse order, try to select instruction using Fast ISel, if it cannot handle instruction it fallbacks to SelectionDAGISel
for these instructions if it is a call and continue fast instruction selections.

However if unhandled instruction is not a call or statepoint related instruction it fallbacks to SelectionDAGISel for all remaining
instructions in basic block.

However gc.result instruction is missed and as a result it is possible that gc.result is processed earlier than statepoint
causing breakage invariant the gc.results should be handled after statepoint.

Test is updated because in the current form fast-isel cannot handle ret instruction (due to i1 ret type without explicit ext)
and as a result test does not check fast-isel at all.
