BSD toolchain contains a bug:
https://sourceforge.net/p/elftoolchain/tickets/491/

In short demangler works differently, fix was to update the testcase.
It should fix the FreeBSD bot failture:
http://lab.llvm.org:8011/builders/lld-x86_64-freebsd/builds/19432/steps/test_lld/logs/stdio

Original commit message was:
[ELF] - Implement extern "c++" version script tag

Patch implements 'extern' version script tag.
Currently only values in quotes(") are supported.

Matching of externs is performed in the same pass as exact match of globals.

SymbolVersions sounds like it had versions for a symbol, so rename it.

llvm-svn: 275674

The identifier `Version` was used too often in the code to handle
symbol versions. The struct that contains version definitions is
named `Version`. Local variables for version ID are named `Version`.
Local varaible for version string are named `Version`.

This patch give them different names.

skip(S) consumes a token if the next token is S,
so it can be used instead of peek() & next().

Previously, Verdefs and Verdauxs are separated in the section.
The new layout is easier to write as we do not have to maintain
two pointers and can avoid passing a reference to a pointer.

In a linker script, `.` is a special symbol indicating a counter.
Previously, we had two expression types, ExprKind and SymbolAssignmentKind
for `.` and all the other symbol names, respectively. But we could merge
them because the former is a special case of the latter.

We should write to ErrorOS instead. Normaly, *ErrorOS == errs(),
but they can be different if LLD is embedded.

This patch corresponds to r275511 for COFF.

Previously, it checked for the EC parameter and set HasError
only when there was an error. But in most places we called
error only when error had occurred, so this behavior was confusing.

ELF spec says that alignment of 0 is equivalent to 1.
Previously, we arbitrary set to 0 or 1, but always setting to 1
makes our program simpler.

r275301 made .got section be aligned on Target->GotEntrySize,
so GotEntrySize must have been initialized. We didn't initialize
it for AMDGPU.

Patch by H.J Lu.

For x86-64 psABI, the entry size of .got and .got.plt sections is 8
bytes for both LP64 and ILP32.  Add GotEntrySize and GotPltEntrySize
to ELF target instead of using size of ELFT::uint.  Now we can generate
a simple working x32 executable.

Config members are named after corresponding command line options.
This patch renames VAStart ImageBase so that they are in line with
--image-base.

Minor cleanup.
Currently it looks wierd that having method addPredefinedSections()
we still add 2 sections outside it without real reasons.
Patch fixes that.
