  Log Message:
  -----------
  [LLDB] [PECOFF] Factorize mapping section names to types using StringSwitch. NFCI.

Keep the existing special cases based on combinations of section name,
flags and sizes/offsets.

  Changed paths:

    A lldb/test/Shell/ObjectFile/PECOFF/section-types.yaml

  Log Message:
  -----------
  [LLDB] [PECOFF] Look for the truncated ".eh_fram" section name

COFF section names can either be stored truncated to 8 chars, in the
section header, or as a longer section name, stored separately in the
string table.

libunwind locates the .eh_frame section by runtime introspection,
which only works for section names stored in the section header (as
the string table isn't mapped at runtime). To support this behaviour,
lld always truncates the section names for sections that will be
mapped, like .eh_frame.

  Log Message:
  -----------
  [LLDB] Always interpret arm instructions as thumb on windows

Windows on ARM always uses thumb mode, and doesn't have most of the
mechanisms that are used in e.g. ELF for distinguishing between arm
and thumb.
