Clang format produces code which does not compile with clang

When using the clang-format options:
```
IntegerLiteralSeparator:
BinaryMinDigits: 16
Binary: 8
Decimal: 3
DecimalMinDigits: 6
Hex: 2
HexMinDigits: 8
```
To insert decimal separators it can produce the following code.
```
#if __cpp_lib_source_location < 201'907L
```
where a decimal separator is added in the preprocessor constant.
It seems clang cannot compile this unless at least c++14 is used.

However even when setting:
```
Standard: c++11
```
clang format still adds the decimal separator.
Further more
```
#if __cpp_lib_source_location < 201'907L
#endif
```
works using:
* `clang -std=c++14 -E test.hpp`
does not work using
* ` clang -std=c++11 -E test.hpp`
* `clang-scan-deps -format=p1689 -- clang -std=c++14 test.hpp`
So it seems clang-format is producing wrong results and clang-scan-deps is ignoring `-std=c++14`
