When spilling, copies from exec can be folded directly

This only fixes the operand constraints, more codegen
work is required to avoid emitting the invalid

This sort of breaks the dbg.value test. Because the

is a copy to SReg_64, and the copy is the operand
of dbg_value. The copy is later dead, and removed

Use relocations to fill statically known got entries.
Right now we just remember a SymbolBody for each got entry and
duplicate a bit of logic to decide what value, if any, should be
written for that SymbolBody.
With ARM there will be more complicated values, and it seems better to
just use the relocation code to fill the got entries. This makes it
clear that each entry is filled by the dynamic linker or by the static
linker.

builtins: switch to c11 from c99
This fixes an incorrect standard usage of GNU99 when the compiler check was for
the ISO standard C99. Furthermore, bump the dependency up to C11. The
motivation for this change is ARM EHABI compatibility with clang 3.8. We rely
on a type definition redefinition which causes an error with -Werror builds.
This is problematic for FreeBSD builds. Switching to C11 allows the
compatibility without the unnecessary pedantic warning. The alternative would
be to clutter the support header with a `pragma clang diagnostic ignore`. GCC
4.8+ and the supported clang revisions along with MSVC support enough of C11 to
allow building the builtins in C11 mode. No functional change intended.

Bitcode: Change expected layout of module blocks.
We now expect each module's identification block to appear immediately before
the module block. Any module block that appears without an identification block
immediately before it is interpreted as if it does not have a module block.
Also change the interpretation of VST and function offsets in bitcode.
The offset is always taken as relative to the start of the identification
(or module if not present) block, minus one word. This corresponds to the
historical interpretation of offsets, i.e. relative to the start of the file.
These changes allow for bitcode modules to be concatenated by copying bytes.
