187ce544b2 Do relaxations with FT_Org fragments. Fixes the FIXME: 
// FIXME: We should compute this sooner, we don't want to recurse here, and
    // we would like to be more functional.

In MCAssembler::ComputeFragmentSize.

d19ec05e07 refactor/cleanup MatchableInfo by eliminating the Tokens array, 
merging it into a Token field in Operand, and moving the first
token to an explicit mnemonic field.  These were parallel
arrays before (except for the mnemonic) which kept confusing me.

371e82bf51 Don't try to split weird critical edges that really aren't: 
BB#1: derived from LLVM BB %bb.nph28
    Live Ins: %AL
    Predecessors according to CFG: BB#0
	TEST8rr %reg16384<kill>, %reg16384, %EFLAGS<imp-def>; GR8:%reg16384
	JNE_4 <BB#2>, %EFLAGS<imp-use,kill>
	JMP_4 <BB#2>
    Successors according to CFG: BB#2 BB#2

These double CFG edges only ever occur in bugpoint-generated code, so there is
no need to attempt something clever.

962c71089d Be more precise about verifying missing kill flags. 
It is legal for an instruction to have two operands using the same register,
only one a kill. This is interpreted as a kill.

3d4114c464 When inserting copies during splitting, always use the parent register as the 
source, and let rewrite() clean it up.

This way, kill flags on the inserted copies are fixed as well during rewrite().

We can't just assume that all the copies we insert are going to be kills since
critical edges into loop headers sometimes require both source and dest to be
live out of a block.
