Nico Weber fb5fafb23c Make LLVM_APPEND_VC_REV=OFF affect clang, lld, and lldb as well. 
When LLVM_APPEND_VC_REV=OFF is set, the current git hash is no
longer embedded into binaries (mostly for --version output).
Without it, most binaries need to relink after every single
commit, even if they didn't change otherwise (due to, say,
a documentation-only commit).

LLVM_APPEND_VC_REV is ON by default, so this doesn't change the
default behavior of anything.

With this, all clients of GenerateVersionFromVCS.cmake honor
LLVM_APPEND_VC_REV.

Rui Ueyama 04661e1084 Update `ld.lld --version` string for monorepo. 
This patch basically does the same thing as
https://reviews.llvm.org/rL352729 did to clang.

With this patch, lld now prints out a correct version string including
a git commit id like this:

  $ bin/ld.lld --version
  LLD 9.0.0 (https://github.com/llvm/llvm-project.git c027658504fa9e68173f53dedaf223695a65e910) (compatible with GNU linkers)

Zachary Turner 727f153b6f [coff] Print detailed timing information with /TIME. 
The classes used to print and update time information are in
common, so other linkers could use this as well if desired.

Bob Haarman b8a59c8aa5 [lld] unified COFF and ELF error handling on new Common/ErrorHandler 
Summary:
The COFF linker and the ELF linker have long had similar but separate
Error.h and Error.cpp files to implement error handling. This change
introduces new error handling code in Common/ErrorHandler.h, changes the
COFF and ELF linkers to use it, and removes the old, separate
implementations.

New lld's files are spread under lib subdirectory, and it isn't easy
to find which files are actually maintained. This patch moves maintained
files to Common subdirectory.
