Generate the DWARF stack frame decode operations in the function prologue for ARM/Thumb functions. Patch by Keith Walker! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@201423 91177308-0d34-0410-b5e6-96231b3b80d8

; ARM EHABI integrated test
; This test case checks whether the ARM DWARF stack frame directives
; are properly generated or not.
; We have to check several cases:
; (1) arm with -disable-fp-elim
; (2) arm without -disable-fp-elim
; (3) armv7 with -disable-fp-elim
; (4) armv7 without -disable-fp-elim
; (5) thumb with -disable-fp-elim
; (6) thumb without -disable-fp-elim
; (7) thumbv7 with -disable-fp-elim
; (8) thumbv7 without -disable-fp-elim
[ARM] Use symbolic register names in .cfi directives only with IAS (PR19110) This is a follow-up to r203635. Saleem pointed out that since symbolic register names are much easier to read, it would be good if we could turn them off only when we really need to because we're using an external assembler.

[ARM] Use symbolic register names in .cfi directives only with IAS (PR19110) This is a follow-up to r203635. Saleem pointed out that since symbolic register names are much easier to read, it would be good if we could turn them off only when we really need to because we're using an external assembler.
