[clang-format] Look at NoLineBreak and NoLineBreakInOperand before breakProtrudingToken

Summary:
This patch makes ContinuationIndenter call breakProtrudingToken only if
NoLineBreak and NoLineBreakInOperand is false.

Previously, clang-format required two runs to converge on the following example with 24 columns:
Note that the second operand shouldn't be splitted according to NoLineBreakInOperand, but the
token breaker doesn't take that into account:
```
func(a, "long long long long", c);
```
After first run:
```
func(a, "long long "
        "long long",
         c);
```
After second run, where NoLineBreakInOperand is taken into account:
```
func(a,
     "long long "
     "long long",
     c);
```

With the patch, clang-format now obtains in one run:
```
func(a,
     "long long long"
     "long",
     c);
```
which is a better token split overall.
