Simon Atanasyan 5606dac67e [ELF] Allow TargetLayout descendants to control assignment sections to segments
The TargetLayout class puts two sections into the same segment if they
have equal segment types and the same section flags (SHF_xxx). To be
able to merge some sort of sections into the same segment we drop some
flags before comparison. For example to merge string sections into Data
segment we drop SHF_STRINGS and SHF_MERGE flags.

The patch allows TargetLayout descendants to drop some target specific
section flags. MIPS target needs that to merge .MIPS.options section
which has SHF_MIPS_NOSTRIP flag into the LOAD segment.

Simon Atanasyan acd58af7df [ELF] Change return type of the OutputSection::flags() method
This method returns _flags field which has `uint64_t` type. Now the
field's type and the method's return type are consistent.

Simon Atanasyan 72026b013b [ELF] Narrow down the type of OutputSection::_sections container
The `OutputSection::appendSection()` method always gets a pointer
to the `Section` class descendants. So it is not necessary to keep them
in the vector of `Chunk` pointers.

No functional changes.
