This worked initially but was broken by r210887.

Before:
  function outer1(a, b) {
    function inner1(a, b) { return a; } inner1(a, b);
  } function outer2(a, b) { function inner2(a, b) { return a; } inner2(a, b); }

After:
  function outer1(a, b) {
    function inner1(a, b) { return a; }
    inner1(a, b);
  }
  function outer2(a, b) {
    function inner2(a, b) { return a; }
    inner2(a, b);
  }

These don't actually require any registered backend to run.

This commit tests the water with a handful of fixes for what is a more
widespread problem.

Add sign checks to deal with the fact that IR parser line/column pairs are
signed integers and sometimes invalid.

The crash path is potentially triggered by corrupt '.bc' files in practice,
though I don't have a binary input test case that can be checked-in right now.

(Unfortunately the backend itself crashes on various ill-formed '.bc' inputs so
this bandage isn't as helpful as it appears yet.)

We'll want to share the implementation if anything else decides to check
for reserved names in future, so make this little snippet of code more
discoverable.

Also remove the __va_list_tag and __builtin_va_list special-case
checks. They're leftovers from before when the reserved name logic was
added.

No change in functionality.

Windows on ARM defines va_list as a typedef for char *.  Although the semantics
of argument passing for variadic functions matches AAPCS VFP, the wrapped
struct __va_list type is unused.  This makes the intrinsic definition for
va_list match that of Visual Studio.

Revert r211866, r211895 and r211995, "Driver: use GNU::Link for the Generic_GCC toolchain". It broke users of Generic_GCC, cygwin and mingw32.

This adds a linker tool for the Windows cygwin environment.  This linker
invocation is significantly different from the generic ld invocation.  It
requires additional parameters as well as does not accept some normal
parameters.  This should fix self-hosting on Cygwin.

Itanium targets.  Add an explicit test to exsure that exceptions are handled
correctly for Windows Itanium environments.
