Summary:
This test only works on systems capable of outputting UTF-8 encoded
text on the standard output (tested on linux and OS X, should XFAIL on windows,
if I haven't messed up the XFAIL line).

This is at least good documentation, but also opens the possibility of
using pipefail.

This is a missing piece for C99 conformance.
This patch handles UCNs by adding a '\\' case to LexTokenInternal and
LexIdentifier -- if we see a backslash, we tentatively try to read in a UCN.
If the UCN is not syntactically well-formed, we fall back to the old
treatment: a backslash followed by an identifier beginning with 'u' (or 'U').
Because the spelling of an identifier with UCNs still has the UCN in it, we
need to convert that to UTF-8 in Preprocessor::LookUpIdentifierInfo.
Of course, valid code that does *not* use UCNs will see only a very minimal
performance hit (checks after each identifier for non-ASCII characters,
checks when converting raw_identifiers to identifiers that they do not
contain UCNs, and checks when getting the spelling of an identifier that it
does not contain a UCN).
This patch also adds basic support for actual UTF-8 in the source. This is
treated almost exactly the same as UCNs except that we consider stray
Unicode characters to be mistakes and offer a fixit to remove them.

This time, make sure we don't try to print fixits with newline characters,
since they don't have a valid column width, and they don't look good anyway.

This should fix the failure on Windows.

This code is very sensitive to the difference between "columns" as printed
and "bytes" (SourceManager columns). All variables are now named explicitly
and our assumptions are (hopefully) documented as both comment and assertion.
Whether parseable fixits should use byte offsets or Unicode character counts
is pending discussion on the mailing list; currently the implementation uses
bytes (and has no problems on lines containing multibyte characters).
This has been added to the user manual.

depends on locale settings.
If a non-unicode locale is used, the unicode character is escaped and any
byte that is in the escaped representation but not the semicolon will
become whitespace.
