For PR411:
This patch is an incremental step towards supporting a flat symbol table.
It de-overloads the intrinsic functions by providing type-specific intrinsics
and arranging for automatically upgrading from the old overloaded name to
the new non-overloaded name. Specifically:
  llvm.isunordered -> llvm.isunordered.f32, llvm.isunordered.f64
  llvm.sqrt -> llvm.sqrt.f32, llvm.sqrt.f64
  llvm.ctpop -> llvm.ctpop.i8, llvm.ctpop.i16, llvm.ctpop.i32, llvm.ctpop.i64
  llvm.ctlz -> llvm.ctlz.i8, llvm.ctlz.i16, llvm.ctlz.i32, llvm.ctlz.i64
  llvm.cttz -> llvm.cttz.i8, llvm.cttz.i16, llvm.cttz.i32, llvm.cttz.i64
New code should not use the overloaded intrinsic names. Warnings will be
emitted if they are used.

Silly Sparc is big endian.  If we have to load args out of incoming stack slots

this into consideration.

Don't print a label for the first MBB in a function.

Compile this:

implementation   ; Functions:
declare int %printf(sbyte*, ...)
void %test()
        %tmp.101 = call int (sbyte*, ...)* %printf( sbyte* getelementptr ([75 x sbyte]* %_2E_str_8, int 0, int 0) )             ; <int> [#uses=0]
        unreachable
}

to this:

main_endif_2E_8:
        save -96, %o6, %o6
        sethi %hi(_2E_str_8), %l0
        add %l0, %lo(_2E_str_8), %o0
        call printf
        nop

instead of this:

main_endif_2E_8:
        save -96, %o6, %o6
        sethi %hi(_2E_str_8), %l0
        or %g0, %lo(_2E_str_8), %l1   ;; extra instruction
        add %l1, %l0, %o0
        call printf
        nop
