Verify that llvm-ar uses COFF archive format by ensuring that archive map is sorted.

RUN: rm -rf %t.dir && split-file %s %t.dir && cd %t.dir

RUN: yaml2obj coff-symtab.yaml -o coff-symtab.obj
RUN: llvm-ar crs out.a coff-symtab.obj

RUN: yaml2obj elf.yaml -o coff-symtab.o
RUN: llvm-ar crs --format coff out3.a coff-symtab.o
RUN: llvm-nm --print-armap out3.a | FileCheck %s

Create an empty archive with no symbol map, add a COFF file to it and check that the output archive is a COFF archive.

RUN: llvm-ar --format coff rcS out4.a
RUN: llvm-ar rs out4.a coff-symtab.obj
RUN: llvm-nm --print-armap out4.a | FileCheck %s
