[Qemu-devel] [PATCH] remove tcg_global_reg2_new_hack()

[Stuart Brady <sdbrady@ntlworld.com>]

This patch removes the unused tcg_global_reg2_new_hack() function, which
was added in r4438 to work around a register shortage problem regarding
dyngen.  The only ever user of this function was removed in r4577.
