Subject: Use size_type for operator[].
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=dada992be7f08c35cc70b5aaf32469d4a86e0225;p=oota-llvm.git

Use size_type for operator[].

This matches std::vector and is more efficient as it avoids
truncations.

With this the text segment of opt goes from 19705442 bytes
to 19703930 bytes.
