39482dde66 Input files should go before all other options. 
Important, for example, when calling 'gcc a.o b.o c.o -lD -lE -lF'.

e3cc3f3c84 Instead of printing unnecessary basic block labels as labels in 
verbose-asm mode, print comments instead. This eliminates a non-comment
difference between verbose-asm mode and non-verbose-asm mode.

Also, factor out the relevant code out of all the targets and into
target-independent code.

5adb66a646 Make ARM and Thumb2 32-bit immediate materialization into a single 32-bit pseudo 
instruction. This makes it re-materializable.

Thumb2 will split it back out into two instructions so IT pass will generate the
right mask. Also, this expose opportunies to optimize the movw to a 16-bit move.

0e6b590b91 Coalescer should not delete extract_subreg, insert_subreg, and subreg_to_reg of 
physical registers. This is especially critical for the later two since they
start the live interval of a super-register. e.g.
%DO<def> = INSERT_SUBREG %D0<undef>, %S0<kill>, 1
If this instruction is eliminated, the register scavenger will not be happy as
D0 is not defined previously.
This fixes PR5055.

9450b0e1a6 Move the dominator verification code out of special code embedded within 
the PassManager code into a regular verifyAnalysis method.

Also, reorganize loop verification. Make the LoopPass infrastructure
call verifyLoop as needed instead of having LoopInfo::verifyAnalysis
check every loop in the function after each looop pass. Add a new
command-line argument, -verify-loop-info, to enable the expensive
full checking.
