Target->RelativeRel is used for all platforms, but AMDGPU did

Summary:
VERSION commands define symbol versions. The grammar of the
commnad is as follows

  VERSION { version-script-commands }

where version-script-commands is

  [ name ] { version-definitions }.

Note that we already support version-script-commands because
it is being used for version script command.

This patch is based on George's patch https://reviews.llvm.org/D23609

As stated in PR28843:

we should handle command lines with

--demangle --no-demangle
Patch implements this for specified options.
There are probably other conflicting options can exist,
so fix is called "partial".

llvm-svn: 280068

Previously for extern keyword only names in quotes (exact match) was supported.
Patch adds support for wildcards, so next scripts can be handled properly:

LIBSAMPLE_1.0 {
   global:            
     extern "C++" {  
       foo*;

The IMAGE_FILE_HEADER structure contains a (RVA, size) to an array of
COFF_DEBUG_DIRECTORY records. Each one of these records contains an RVA to a OMF
Debug Directory. These OMF debug directories are derived into newer types such
as PDB70, PDB20, etc. This constructs a PDB70 structure which will allow us to
associate a GUID with a build to actually tie debug information.

The ARM Exception handling ABI requires that all ARM exception index
table sections have a prefix of .ARM.exidx and are combined into a
single contiguous block either in their own output section or as part
of another output section.
    
In general clang will output a single .ARM.exidx section per object,
but will use .ARM.exidx.<section name> when -ffunction-sections is used.
    
This change canonicalizes the names of sections with the .ARM.exidx
prefix to just .ARM.exidx, which ensures that there is only a single
output section.
