Avoid overwriting the APInt instance with 0 bytes which causes the bitwidth
to be set to 0 (illegal) producing a subsequent assert.

Remove a bogus check. Even terminators in a ifcvt need to be predicated. Unconditional branches can usually be converted to conditional ones.

specify a minimum alignment if needed.  This fixes some objc protocol
failures Devang tracked down.

For VFP2 fldm, fstm instructions, the condition code is printed after the address mode and size specifier. e.g. fstmiaseq, not fstmeqias.
