In Thumb mode we cannot handle GPR virtual registers, even though some instructions can. When isel is lowering a CopyFromReg, it should limit itself to subclasses of getRegClassFor(VT). <rdar://problem/9624323> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@133210 91177308-0d34-0410-b5e6-96231b3b80d8

; This test would crash because isel creates a GPR register for the return
|
|
; value from f1. The register is only used by tBLXr_r9 which accepts a full GPR
|
|
; register, but we cannot have live GPRs in thumb mode because we don't know how
|
|
; to spill them.
