[ELF] - Fix BB after r324463. Test requires arm, but specified x86. llvm-svn: 324464

# REQUIRES: arm
[ELF] - Represent tests as linker scripts instead of asm. This follows recently started direction and sometimes allows to fully get rid from `echo` calls. I'll rename changed files to *.test in a follow-up. llvm-svn: 327410

# RUN: llvm-mc -filetype=obj -triple=armv7-unknown-linux-gnueabi /dev/null -o %t.o
[ELF] - Remove unused synthetic sections correctly. This is PR35740 which now crashes because we remove unused synthetic sections incorrectly. We can keep input section description and corresponding output section live even if it must be empty and dead. This results in a crash because SHF_LINK_ORDER handling code tries to access first section which is nullptr in this case. Patch fixes the issue. Differential revision: https://reviews.llvm.org/D42681 llvm-svn: 324463

## We incorrectly removed unused synthetic sections and crashed before.
## Check we do not crash and do not produce .trap output section.
