[MIPS GlobalISel] Add detailed tests for lower call
Test different operand types of callee and their behavior whether relocation model is pic or not. Possible operand types are: Register (function pointer), External symbol (used for libcalls e.g. __udivdi3 or memcpy), Global address. Global address has different handling depending on relocation model and linkage type. Register and external symbol do not. Differential Revision: https://reviews.llvm.org/D62590 llvm-svn: 362212
