Go patch committed: Remove name_ field from Type_switch_statement

[Ian Lance Taylor]

[-- Attachment #1: Type: text/plain, Size: 208 bytes --]

This patch to the Go frontend removes the name_ field from the
Type_switch_statement class.  It's not used for anything.
Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.  Committed
to mainline.
