Improve performance TokenizeWindowsCommandLine
Patcy by Takuto Ikuta.
This patch reduces lld link time of chromium's blink_core.dll in
component build.
Total size of input argument in .directives become nearly 300MB in the
build and calling many strchr and assert becomes bottleneck.
On my desktop machine, 4 times stats of the link time are like below.
Improved around 10%.
