This requires std::intializer_list to be a literal type, which it is
starting with C++14. The downside is that std::bitset is still not
constexpr-friendly so this change contains a re-implementation of most
of it.
Shrinks clang by ~60k.

One problem with untagging memory in landing pads is that it only works
correctly if the function that catches the exception is instrumented.
If the function is uninstrumented, we have no opportunity to untag the
memory.
To address this, replace landing pad instrumentation with personality function
wrapping. Each function with an instrumented stack has its personality function
replaced with a wrapper provided by the runtime. Functions that did not have
a personality function to begin with also get wrappers if they may be unwound
past. As the unwinder calls personality functions during stack unwinding,
the original personality function is called and the function's stack frame is
untagged by the wrapper if the personality function instructs the unwinder
to keep unwinding. If unwinding stops at a landing pad, the function is
still responsible for untagging its stack frame if it resumes unwinding.
The old landing pad mechanism is preserved for compatibility with old runtimes.

Without this patch, failing to provide a subcommand to lit's internal
`env` results in either a python `IndexError` or an attempt to execute
the final `env` argument, such as `FOO=1`, as a command. This patch
diagnoses those cases with a more helpful message.

Renames GTEST_NO_LLVM_RAW_OSTREAM -> GTEST_NO_LLVM_SUPPORT and guards
the new features behind it.

Summary:
These are detected by gtest as containers, and so previously printed as e.g.
{ '.' (46, 0x2E), 's' (115, 0x73), 'e' (101, 0x65), 'c' (99, 0x63), '0' (48, 0x30) },
gtest itself overloads PrintTo for std::string and friends, we use the same mechanism.

Overloaded intrinsics can use iPTRAny in used/input operands.
The GlobalISelEmitter doesn't know that these are pointers, so it treats them
as scalars. As a result, these intrinsics can't be imported.
This teaches the GlobalISelEmitter to recognize these as pointers rather than
scalars.

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.

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.
