ART: Fix GenInlined functions

This patch fixes Mir2Lir::GenInlinedReverseBytes,
Mir2Lir::GenInlinedAbsInt, Mir2Lir::GenInlinedAbsLong,
Mir2Lir::GenInlinedFloatCvt, Mir2Lir::GenInlinedDoubleCvt,
X86Mir2Lir::GenInlinedSqrt, X86Mir2Lir::GenInlinedMinMaxFP,
X86Mir2Lir::GenInlinedMinMax, X86Mir2Lir::GenInlinedPeek,
and X86Mir2Lir::GenInlinedReverseBits to generate no code, when results
are unused.
New calls without assignments are added to 082-inline-execute.
