George Rimar 469cb2e814 [llvm-objcopy] - Report SHT_GROUP sections with invalid alignment. 
This patch fixes the reason of ubsan failure (UB detected) 
happened after landing the D59638 (I had to revert it).
http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-bootstrap-ubsan/builds/11760/steps/check-llvm%20ubsan/logs/stdio)

Problem is the following. Our implementation of GroupSection assumes that
its address is 4 bytes aligned when writes it:

template <class ELFT>
void ELFSectionWriter<ELFT>::visit(const GroupSection &Sec) {
  ELF::Elf32_Word *Buf =
      reinterpret_cast<ELF::Elf32_Word *>(Out.getBufferStart() + Sec.Offset);
...

But the test case for D59638 did not set AddressAlign in YAML. So address was
not 4 bytes aligned since Sec.Offset was odd. That triggered the issue.

This patch teaches llvm-objcopy to report an error for such sections (which should
not met in reality), what is better than having UB.
