The classes used to print and update time information are in
common, so other linkers could use this as well if desired.

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.

Summary:
This will allow using the functionality from other linkers. It is also
a prerequisite for sharing the error logging code.

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.
