Fix a bug in the DAGCombiner's handling of multiple linked
...
MERGE_VALUES nodes. Replacing the result values with the
operands in one MERGE_VALUES node may cause another
MERGE_VALUES node be CSE'd with the first one, and bring
its uses along, so that the first one isn't dead, as this
code expects. Fix this by iterating until the node is
really dead. This fixes PR4699.

fix a couple of problems with section attributes:
...
1. Passing something that isn't a string used to cause:
"argument to annotate attribute was not a string literal"
make it say "section attribute" instead.
2. Fix the location of the above message to point to the
bad argument instead of the section token.
3. Implement rdar://4341926, by diagnosing invalid section
specifiers in the frontend rather than letting them slip all
the way to the assembler (a QoI win).
An example of #3 is that we used to produce something like this:
/var/folders/n7/n7Yno9ihEm894640nJdSQU+++TI/-Tmp-//ccFPFGtT.s:2:Expected comma after segment-name
/var/folders/n7/n7Yno9ihEm894640nJdSQU+++TI/-Tmp-//ccFPFGtT.s:2:Rest of line ignored. 1st junk character valued 46 (.).
Daniel improved clang to use llvm_report_error, so now we got:
$ clang t.c -c
fatal error: error in backend: Global variable 'x' has an invalid section specifier 'sadf': mach-o section specifier
requires a segment and section separated by a comma.
with no loc info. Now we get:
$ clang t.c -fsyntax-only
t.c:4:30: error: argument to 'section' attribute is not valid for this target: mach-o section specifier requires a segment
and section separated by a comma
int x __attribute__((section("sadf")));
^
which is nice :)

...
ld: bad offset (0x00000091) for lo14 instruction pic-base fix-up in ___popcountdi2 from libgcc/./_popcountsi2_s.o
The problem is that the non lazy symbol pointers need to be 8 byte aligned
on ppc64 and .section doesn't have an implicit alignment like ".non_lazy_symbol_pointer"
does.
