[vm/compiler] Instroduce SIMARM_X64 build architecture. This is variant of SIMARM build (ARM target and non-ARM host) but with a word size mismatch (32-bit target and 64-bit host). We only expect to build gen_snapshot binary in this mode. This is the first step towards enabling AOT compilation targeting ARM using 64-bit gen_snapshot binary. This change also introduces --gen-snapshot flag for test.py which allows to specify which gen_snapshot binary should be used for running tests. Expected workflow with SIMARM_X64 build: $ tools/build.py -a simarm_x64 -m release gen_snapshot $ tools/build.py -a simarm -m release dart_precompiled_runtime vm_platform $ tools/test.py -a simarm -m release -c dartkp --gen-snapshot out/ReleaseSIMARM_X64/gen_snapshot Note that our ARM simulator can't be built as a 64-binary so we are going to be using SIMARM runtime to test AOT compiled code produced by SIMARM_X64 binary.
