Fangrui Song 8bc7bc4570 [Support] Allow FileOutputBuffer::create to create an empty file 
Size==0 triggers `assert(Size != 0)` in mapped_file_region::init.
I plan to use an empty file in D79339 (llvm-objcopy --dump-section).

According to POSIX, "If len is zero, mmap() shall fail and no mapping
shall be established." Just specialize case Size=0 to use
createInMemoryBuffer.
