Some bit-set fields used in ELF file headers in fact contain two parts.
The first one is a regular bit-field. The second one is an enumeraion.
For example ELF header `e_flags` for MIPS target might contain the
following values:
Bit-set values:
EF_MIPS_NOREORDER = 0x00000001
EF_MIPS_PIC = 0x00000002
EF_MIPS_CPIC = 0x00000004
EF_MIPS_ABI2 = 0x00000020
Enumeration:
EF_MIPS_ARCH_32 = 0x50000000
EF_MIPS_ARCH_64 = 0x60000000
EF_MIPS_ARCH_32R2 = 0x70000000
EF_MIPS_ARCH_64R2 = 0x80000000
For printing bit-sets we use the `yaml::IO::bitSetCase()`. It does not
support bit-set/enumeration combinations and prints too many flags from
an enumeration part. This patch fixes this problem. New method
`yaml::IO::maskedBitSetCase()` handle "enumeration" part of bitset
defined by provided mask.
Patch reviewed by Nick Kledzik and Sean Silva.

MappingTrait template specializations can now have a validate() method which
performs semantic checking. For details, see <http://llvm.org/docs/YamlIO.html>.

Before we learned about :doc:, we used :ref: and put a dummy link at the
top of each page. Don't do that anymore.
This fixes PR14891 as a special case.
