Add a check for the VC++ 2012-style 64-bit path.
In VS2012 the path to the 64-bit tools has changed to
VCINSTALLDIR\bin\x86_amd64\cl.exe. This change will make the bootstrap
check there to see if it exists before falling back to the old amd64 path.

Fix duplicate edge Pool crash in the minimally invasive way
Add spell checking for debug flags.

I just used `ninja -d stat` and it took me a bit to realize that I missed the
trailing 's'.

While here, move the message printing from printf() to Error(). This makes the
output consistent with other error outputs: The messages are now prefixed with
"ninja: error: " instead of just "ninja: " and they go to stderr instead of
stdout.
