Description
On #6242 Han reported the following test failure:
```
[junit4] FAILURE 0.27s | TestRangeAccumulator.testMissingValues <<<
[junit4] > Throwable #1: org.junit.ComparisonFailure: expected:<...(0)
[junit4] > less than 10 ([8)
[junit4] > less than or equal to 10 (]8)
[junit4] > over 90 (8)

[junit4] > less than 10 ([28)
[junit4] > less than or equal to 10 (2]8)

[junit4] > at org.apache.lucene.facet.range.TestRangeAccumulator.testMissingValues(TestRangeAccumulator.java:670)
[junit4] > at java.lang.Thread.run(Thread.java:722)
```
which can be reproduced with
```
tcase=TestRangeAccumulator -Dtests.method=testMissingValues -Dtests.seed=815B6AA86D05329C -Dtests.slow=true -Dtests.postingsformat=Lucene41 -Dtests.locale=ca -Dtests.timezone=Australia/Currie -Dtests.file.encoding=UTF-8
```
It seems that the Codec that is picked is a Lucene45Codec with Lucene42DVFormat, which does not support docsWithFields for numericDV. We should improve LTC.defaultCodecSupportsDocsWithField to take a list of fields and check that the actual DVF used for each field supports it.
