Duncan P. N. Exon Smith b011ad7330 LTO: Verify the input even if optimize() isn't called

Clients may call writeMergedModules before calling optimize, or call
compileOptimized without calling optimize.  Make sure they don't sneak
past the verifier.  This adds LTOCodeGenerator::verifyMergedModuleOnce,
and calls it from writeMergedModule, optimize, and codegenOptimized.

I couldn't find a good way to test this.  I tried writing broken IR to
send into llvm-lto, but LTOCodeGenerator doesn't understand textual IR,
and assembler runs the verifier itself anyway.  Checking in
valid-but-doesn't-verify bitcode here doesn't seem valuable.
