This patch extends lit's test suite to check that lit's internal shell
doesn't accidentally execute internal commands as external commands.
It does so by putting fake failing versions of those commands in
`PATH` while the entire lit test suite is running. Without the fixes
in D65697 but with its tests, this approach catches accidental
external `env` calls.

These data formatters make the string value appear in Xcode's
variables view (and on the command line) without having to expand the
data structure.

AMDGPU has some buffer intrinsics which theoretically could use
this. Some of the generated tables include the 3 and 4 element vector
versions of these rounded to 64-bits, which is ambiguous. Add these to
help the table disambiguate these.
Assertion change is for the path odd sized vectors now take for R600.
v3i16 is widened to v4i16, which then needs to be promoted to v4i32.

Now that we've moved to C++14, we no longer need the llvm::make_unique
implementation from STLExtras.h. This patch is a mechanical replacement
of (hopefully) all the llvm::make_unique instances across the monorepo.

Without this patch, `-dump-input` prints a diagnostic at the end of
its marker range. For example:
```
1: Start.
check:1 ^~~~~~
2: Bad.
next:2 X~~~
3: Many lines
next:2 ~~~~~~~~~~
4: of input.
next:2 ~~~~~~~~~
5: End.
next:2 ~~~~ error: no match found
```
This patch moves it to the beginning like this:
```
1: Start.
check:1 ^~~~~~
2: Bad.
next:2 X~~~ error: no match found
3: Many lines
next:2 ~~~~~~~~~~
4: of input.
next:2 ~~~~~~~~~
5: End.
next:2 ~~~~
```
The former somehow looks nicer because the diagnostic doesn't appear
to be somewhere within the marker range. However, the latter is more
practical, especially when the marker range includes the remainder of
a very long dump. First, in the case of an error, this patch enables
me to search the dump for `error:` and usually immediately land where
the detected error began. Second, when trying to follow FileCheck's
logic, it's best to read top down, so this patch enables me to see
each diagnostic as soon as I encounter its marker.

Summary:
The problem:
When an operand had bits explicitly set to "1" (as in the InitValue.td test case attached), the decoder was ignoring those bits, and the DecoderMethod was receiving an input where the bits were still zero.
The solution:
We added an "InitValue" variable that stores the initial value of the operand based on what bits were explicitly initialized to 1 in TableGen code. The generated decoder code then uses that initial value to initialize the "tmp" variable, then calls fieldFromInstruction to read the values for the remaining bits that were left unknown in TableGen.
This is mainly useful when there are variations of an instruction that differ based on what bits are set in the operands, since this change makes it possible to access those bits in a DecoderMethod. The DecoderMethod can use those bits to know how to handle the input.

Summary:
'OSI Approved :: Apache-2.0 with LLVM exception' is not a valid
classifier. 'OSI Approved :: Apache Software License' is the closest
fit for the new license, so we've decided to use this one.
The classifiers seem to only be used for searching on the pypi website,
so this does not actually change the license of the code.
We still pass 'Apache-2.0 with LLVM exception' as the license to setup(),
and this appears alongside the classifier on the pypi webpage for lit.

The upper 4 bits of the immediate byte are used to encode a
register. We need to limit the explicit immediate to fit in the
remaining 4 bits.
