Formatting this piece of code made the program crash.
```
class TypedVecListRegOperand<RegisterClass Reg, int lanes, string eltsize>
: RegisterOperand<Reg, "printTypedVectorList<" # lanes # ", '"
# eltsize # "'>">;
```
The line starting with the `#` was treated as a separate preprocessor
directive line. Then the code dereferenced a null pointer when it tried
to continue parsing the first line that did not end in a semicolon.
Now the 2 problems are fixed.
Summary:
clang-formatting wants to add spaces around items in square braces, e.g. [1, 2] -> [ 1, 2 ]. Based on a quick check [1], it seems like most cases are using the [1, 2] format, so make that the consistent one.
[1] in llvm `.td` files, the regex `\[[^ ]` (bracket followed by not-a-space) shows up ~400 times, but `\[\s[^ ]` (bracket followed by one space and one not-a-space) shows up ~40 times => ~90% uses this format.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
clang-format can get confused by string literals in TableGen: it knows that strings can be broken up, but doesn't seem to understand how that can be indented across line breaks, and arranges them in a weird triangular pattern. Take this output example from `clang-format tools/llvm-objcopy/ObjcopyOpts.td` (which has now been formatted in rL345896 with this patch applied):
```
defm keep_global_symbols
: Eq<
"keep-global-symbols", "Reads a list of symbols from <filename> and "
"runs as if " "--keep-global-symbol=<symbol> "
"is set for each one. "
"<filename> " "contains one "
"symbol per line "
"and may contain "
"comments "
"beginning " "with"
" '#'"
". "
"Lead"
"ing "
```
