Fix two classes of bugs. First:
...
validate an invariant so that the asmparser rejects a bad construct
instead of the verifier. Before:
llvm-as: assembly parsed, but does not verify as correct!
Invalid struct return type!
i64 (%struct.Type*, %struct.Type*)* @foo
after:
llvm-as: t.ll:5:8: functions with 'sret' argument must return void
define i64 @foo(%struct.Type* noalias nocapture sret %agg.result, %struct.Type* nocapture byval %t) nounwind {
^
Second, check that void is only used where allowed (in function return types) not in
arbitrary places, fixing PR3747 - Crash in llvm-as with void field in struct. We
now reject that example with:
$ llvm-as t.ll
llvm-as: t.ll:1:12: struct element can not have void type
%x = type {void}

This also improves the existing pic-cpool case from:

addl $_GLOBAL_OFFSET_TABLE_ + [.-.Lllvm$1.$piclabel], %eax

movsd .LCPI1_1@GOTOFF(%eax), %xmm0
.LBB1_2: # entry
movsd %xmm0, (%esp)
fldl (%esp)
addl $12, %esp
ret
to:
foo:

.Lllvm$1.$piclabel:
popl %eax
addl $_GLOBAL_OFFSET_TABLE_ + [.-.Lllvm$1.$piclabel], %eax
xorl %ecx, %ecx
cmpl $0, 4(%esp)
movl $8, %edx

Introduce new linkage types linkonce_odr, weak_odr, common_odr
...
and extern_weak_odr. These are the same as the non-odr versions,
except that they indicate that the global will only be overridden
by an *equivalent* global. In C, a function with weak linkage can
be overridden by a function which behaves completely differently.
This means that IP passes have to skip weak functions, since any
deductions made from the function definition might be wrong, since
the definition could be replaced by something completely different
at link time. This is not allowed in C++, thanks to the ODR
(One-Definition-Rule): if a function is replaced by another at
link-time, then the new function must be the same as the original
function. If a language knows that a function or other global can
only be overridden by an equivalent global, it can give it the
weak_odr linkage type, and the optimizers will understand that it
is alright to make deductions based on the function body. The
code generators on the other hand map weak and weak_odr linkage
to the same thing.

Finish cross-process JIT work, and clean up previous work.

1. When the JIT is asked to remove a function, updating it's
mapping to 0, we invalidate any function stubs used only
by that function. Now, also invalidate the JIT's mapping
from the GV the stub pointed to, to the address of the GV.
2. When dlsym stubs for cross-process JIT are enabled, do not
abort just because a named function cannot be found in the
JIT's process.
3. Fix various assumptions about when it is ok to use the lazy
resolver when non-lazy JITing is enabled.
