- New ProcessInfo class to encapsulate information about child processes.
- Generalized the Wait() to support non-blocking wait on child processes.
- ExecuteNoWait() now returns a ProcessInfo object with information about
  the launched child. Users will be able to use this object to
  perform non-blocking wait.
- ExecuteNoWait() now accepts an ExecutionFailed param that tells if execution
  failed or not.

These changes will allow users to implement basic process parallel
tools.

YAMLIO printed a string as is without quotes unless it contains a newline
character. That did not suffice. We also need to quote a string if it starts
with a backquote, quote, double quote or atsign, or it's the empty string.

On Windows, character encoding of multibyte environment variable varies
depending on settings. The only reliable way to handle it I think is to use
GetEnvironmentVariableW().

GetEnvironmentVariableW() works on wchar_t string, which is on Windows UTF16
string. That's not ideal because we use UTF-8 as the internal encoding in LLVM.
This patch defines a wrapper function which takes and returns UTF-8 string for
GetEnvironmentVariableW().

The wrapper function does not do any conversion and just forwards the argument
to getenv() on Unix.

The work on this project was left in an unfinished and inconsistent state.
Hopefully someone will eventually get a chance to implement this feature, but
in the meantime, it is better to put things back the way the were.  I have
left support in the bitcode reader to handle the case-range bitcode format,
so that we do not lose bitcode compatibility with the llvm 3.3 release.

Move generic isPrint and columnWidth implementations to a separate header/source to allow using both generic and system-dependent versions on win32.

Summary:
This is needed so we can use generic columnWidthUTF8 in clang-format on
win32 simultaneously with a separate system-dependent implementations of
isPrint/columnWidth in TextDiagnostic.cpp to avoid attempts to print Unicode
characters using narrow-character interfaces (which is not supported on Windows,
and we'll have to figure out how to handle this).

Summary:
This is consistent with MacOSX implementation, and most terminals
actually display this character (checked on gnome-terminal, lxterminal, lxterm,
Terminal.app, iterm2). Actually, this is in line with the ISO Latin 1 standard
(ISO 8859-1), which defines it differently from the Unicode Standard. More
information here: http://www.cs.tut.fi/~jkorpela/shy.html

Implemented llvm::sys::locale::columnWidth and isPrint for the case of generic UTF8-capable terminal.

Summary:
This is a second attempt to get this right. After reading the Unicode
Standard I came up with the code that uses definitions of "printable" and
"column width" more suitable for terminal output (i.e. fixed-width fonts and
special treatment of many control characters).
The implementation here can probably be used for Windows and MacOS if someone
can test it properly.
The patch addresses PR14910.
