5df0e0a61d Rename getAddrModeImm12OpValue to getAddrModeImmOpValue and expand it to work 
with immediates up to 16-bits in size. The same logic is applied to other LDR
encodings, e.g. VLDR, but which use a different immediate bit width (8-bits in
VLDR's case). Removing the "12" allows it to be more generic.

bd6e0323b9 appendSuffix: don't append a dot when the suffix is empty. 
Additionally, move the implementation of appendSuffix to Path.cpp: it is
platform-independent.

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.
