[mips] Make Static a default relocation model for MIPS codegen This change follows up defaults for GCC and Clang, so LLVM does not differ from them. While number of the test files are touched with this change, they all keep the old (expected) behaviour with the explicit option: "-relocation-model=pic" The tests that have not been touched are insensitive to relocation model.

[mips] Make sure there is a chain edge dependency between loads that read formal arguments on the stack and stores created afterwards. We need this to ensure tail call optimized function calls do not write over the argument area of the stack before it is read out. llvm-svn: 194309

[mips] Make sure loads from lazy-binding entries do not get CSE'd or hoisted out of loops. Previously, two consecutive calls to function "func" would result in the following sequence of instructions: 1. load $16, %got(func)($gp) // load address of lazy-binding stub. 2. move $25, $16 3. jalr $25 // jump to lazy-binding stub. 4. nop 5. move $25, $16 6. jalr $25 // jump to lazy-binding stub again. With this patch, the second call directly jumps to func's address, bypassing the lazy-binding resolution routine: 1. load $25, %got(func)($gp) // load address of lazy-binding stub. 2. jalr $25 // jump to lazy-binding stub. 3. nop 4. load $25, %got(func)($gp) // load resolved address of func. 5. jalr $25 // directly jump to func. llvm-svn: 191591
