- Added StringView which is used as a reference to a string, but
doesn't own the string.
- Removed the old string pool in DwarfCUToModule::FilePrivate, since
it's doing string copy.
- Added a string pool in Module to store functions/inline origins'
names (mangled and demangled).
- The peak memory usage drops from 20.6 GB to 12.5 GB when disabling
inline records and drops from 36 GB to 20.3 GB when enabling inline records.

It moves InlineOriginMap to module.h. Let Module keeps the global InlineOriginMap to easily get all referenced InlineOrigin when emitting. And release allocated memory inside its destructor.

This change makes sure dump_syms process DW_TAG_inlined_subroutine only when -d flag is given, which save memory and time when -d is not given. Before this, it always processes DW_TAG_inlined_subroutine and -d determines whether or not to emit INLINE records.

macho_reader assumes that every section in a segment exists, or none of the
sections exist in the file (for dSYM files).
https://reviews.llvm.org/D94460?id=315965 added __eh_frame section to the
__TEXT segments in dSYM files. All the other sections are removed, but still
have non-zero size in the header. macho_reader only looks at `fileoff` and
`filesize` fields to determine the size of the segment, but it looks at `addr`
and `size` to determine the size of the section, therefore it determines that
the sections would not fit in the segment and refused to parse the file.
In this case the removed sections all have offset == 0. Ignore such cases.
