Remove -join-physregs from the test suite. This option has been disabled for a while, and it is going away so I can clean up the coalescer code. The tests that required physreg joining to be enabled were almost all of the form "tiny function with interference between arguments and return value". Such functions are usually inlined in the real world. The problem exposed by phys_subreg_coalesce-3.ll is real, but fairly rare. llvm-svn: 157027

Explicitly request physreg coalesing for a bunch of Thumb2 unit tests. These tests all follow the same pattern: mov r2, r0 movs r0, #0 $CMP r2, r1 it eq moveq r0, #1 bx lr The first 'mov' can be eliminated by rematerializing 'movs r0, #0' below the test instruction: $CMP r0, r1 mov.w r0, #0 it eq moveq r0, #1 bx lr So far, only physreg coalescing can do that. The register allocators won't yet split live ranges just to eliminate copies. They can learn, but this particular problem is not likely to show up in real code. It only appears because r0 is used for both the function argument and return value. llvm-svn: 130858
