  Log Message:
  -----------
  Allow /STACK in #pragma comment(linker, ...)

The Halide project uses `#pragma comment(linker, "/STACK:...")` to set
the stack size high enough for our embedded compiler to run in end-user
programs on Windows.

Unfortunately, lld-link.exe breaks on this when embedded in a COFF
object, despite supporting the flag on the command line. MSVC's link.exe
supports this fine. This patch extends support for this to lld-link.exe
for better compatibility with MSVC projects.
