3892baac42 Clean up the usage of evaluateICmpRelation's return value.
Add another line to the ConstantExprFold test to demonstrate the GEPs may not
wrap around in either the signed or unsigned senses.

5511ffd763 Here's fun! It turns out that these filter functions can be internal. If they're
internal, they shouldn't use the indirect pointer stuff. In the case of
throw_rethrow_test, it was marked as 'internal' and calculated its own offset to
its contents.

99c5c7b7df convert a bunch more stuff to use StringRef. The ArgName arguments are now
stringref because they may not be nul terminated.  For options like -Lfoo
this now avoids a O(n)  temporary std::strings where N is the length of 
the string after -L.

39faac2531 When computing live intervals for earlyclobber operands,
we pushed the beginning of the interval back 1, so the
interval would overlap with inputs that die.  We were
also pushing the end of the interval back 1, though,
which means the earlyclobber didn't overlap with other
output operands.  Don't do this.  PR 4964.

296ab7e544 It's inefficient to have place the exception tables (which contain the LSDA)
into the __DATA section. At launch time, dyld has to update most of the section
to fix up the type info pointers. It's better to place it into the __TEXT
section and use pc-rel indirect pointer encodings. Similar to the personality
routine.
