2021-01-11Fix Go branch for arm64.Adin Scannell
This requires several changes: * Templates must preserve relevant tags. * Pagetables templates are split into two targets, each preserving tags. * The binary VDSO is similarly split into two targets, with some juggling. * The top level tools/go_branch.sh now does a crossbuild of ARM64 as well, and checks and merges the results of the two branches together. Fixes #5178 PiperOrigin-RevId: 351304330

current when save fpsmid register is using following instruction: # FMOVD Fx, 16*1(R0) this instruction will compiled to: # str Dx, [x0, #16] Dx is 64bit fp register not 128bit, then upper 64bit data will be lossed, this will cause application meet many random crash issue. need use 128bit register Vx or Q0 to save and restore the fpsmid context.
