50dbbda454 Don't override the var from the enclosing scope. 
When doing copy/paste/modify, it's apparently rather important to remember
the 'modify' bit...

9b7c2ce591 ARM/Thumb2: Fix a misselect in getARMCmp, when attempting to adjust a signed 
comparison that would overflow.
 - The other under/overflow cases can't actually happen because the immediates
   which would trigger them are legal (so we don't enter this code), but
   adjusted the style to make it clear the transform is always valid.

1544f79e36 Fix nasty mingw32 bug, which e.g. prevented llvm-gcc bootstrap there. 
Mark _alloca call as clobberring EFLAGS, otherwise some DCE might remove
other flags-clobberring stuff (e.g. cmp instructions) occuring after
_alloca call.

ARM instructions with:

e0cdfa265a In the default address space, any GEP off of null results in a trap value if you try to load it. Thus, 
any load in the default address space that completes implies that the base value that it GEP'd from
was not null.

6e1e480f13 Don't include the is-function-local bit in the FoldingSetNodeID 
for MDNodes, since this information is effectively implied by
the operands. This allow allows the code to avoid doing a
recursive is-it-really-function-local check in some cases.

024b04ad93 First bit of support for the dwarf .loc directive. This patch updates the 
needed parsing for the .loc directive and saves the current info from that
into the context.  The next patch will take the current loc info after an
instruction is assembled and save that info into a vector for each section for
use to build the line number tables.  The patch after that will encode the info
from those vectors into the output file as the dwarf line tables.
