79047e7eb3 appendSuffix: don't append a dot when the suffix is empty. 
Additionally, move the implementation of appendSuffix to Path.cpp: it is
platform-independent.

daf6328eb0 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.

breaker needs to check all definitions of the antidepenent register to

6f1fec971e 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.

840357ca6a 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.
