This is the implementation of crrev.com/c/866721 for arm. Drive-by change: I simplified the slot index calculation. Original description: At the moment the slot index is encoded in the opcode. This, however, sets an upper limit the slot index which is lower than what we want to have (i.e. < 512). With this change we pass the slot index as an immediate operand, which does not impose limits on the value it contains.

This is the implementation of crrev.com/c/766371 for arm64. Original description: Add the ability to return (multiple) return values on the stack: - Extend stack frames with a new buffer region for return slots. This region is located at the end of a caller's frame such that its slots can be indexed as caller frame slots in a callee (located beyond its parameters) and assigned return values. - Adjust stack frame constructon and deconstruction accordingly. - Extend linkage computation to support register plus stack returns. - Reserve return slots in caller frame when respective calls occur. - Introduce and generate architecture instructions ('peek') for reading back results from return slots in the caller. - Aggressive tests. - Some minor clean-up.

On Arm64, the 31 encoding refers to either the zero register or the stack pointer depending on the instruction. However, in order to distinguish them in the assembler, the stack pointer has an internal code which isn't 31. As a result, we need to use the internal code when converting a Register to a DWARF code.

This will add three gc fuzzing flags with 5% likelihood each to the second correctness fuzzing config. The random checks are determined by the top-level random-seed passed to the script. This change depends on setting the fuzzer random seed as default to the standard random seed, since the former isn't explicitly passed by clusterfuzz.

On arm64, the stack pointer has to be aligned all the time. This alignment was not considered in the creation of the CallDescriptor in the fuzzer and thereby caused a mismatch between the CallDescriptor and code generator. In other words, a callee put return values in a stack slot which was different than the stack slot where the caller expected the return value. With this CL we consider this alignment in the fuzzer.
