<pre>This causes problems on Windows, where backslashes are common in argument files
because of the file system.
Clang is consistent with GCC here, but if we grow some kind of MSVC-compatible
driver mode, we should not strip the backslashes.
a.c:
foo
a.c.args:
-Dfoo=a\b\c
$ clang -E a.c @a.c.args
# 1 "a.c"
# 1 "<built-in>" 1
# 1 "<built-in>" 3
# 159 "<built-in>" 3
# 1 "<command line>" 1
# 1 "<built-in>" 2
# 1 "a.c" 2
'abc'
$ gcc -E a.c @a.c.args
# 1 "a.c"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "a.c"
'abc'
cl.exe /E a.c @a.c.arg
#line 1 "a.c"
a\b\c</pre>
