runtime: support for debugger function calls on linux/arm64 This CL adds support for debugger function calls on linux arm64 platform. The protocol is basically the same as in CL 109699, except for the following differences: 1, The abi difference which affect parameter passing and frame layout. 2, Stores communication information in R20. 3, The closure register is R26. 4, Use BRK 0 instruction to generate a breakpoint. The saved PC in sigcontext is the PC where the signal occurred, not the next PC. In addition, this CL refactors the existing code (which is dedicated to amd64) for easier multi-arch scaling.
