Implement AsmParser for ARM unwind directives. This commit implements the AsmParser for fnstart, fnend, cantunwind, personality, handlerdata, pad, setfp, save, and vsave directives. This commit fixes some minor issue in the ARMELFStreamer: * The switch back to corresponding section after the .fnend directive. * Emit the unwind opcode while processing .fnend directive if there is no .handlerdata directive. * Emit the unwind opcode to .ARM.extab while processing .handlerdata even if .personality directive does not exist. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@181603 91177308-0d34-0410-b5e6-96231b3b80d8

@ Check the .group section for the function in comdat section.
@ In C++, the instantiation of the template will come with linkonce (or
@ linkonce_odr) linkage, so that the linker can remove the duplicated
@ instantiation. When the exception handling is enabled on those function,
@ we have to group the corresponding .ARM.extab and .ARM.exidx with the
@ text section together.
@
@ This test case will check the content of .group section. The section index
@ of the grouped sections should be recorded in .group section.

Write sections mostly in one pass. During ELF writing, there is no need to further relax the sections, so we should not be creating fragments. This patch avoids doing so in all cases but debug section compression (that is next). Also, the ELF format is fairly simple to write. We can do a single pass over the sections to write them out and compute the section header table. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@236235 91177308-0d34-0410-b5e6-96231b3b80d8
