[mach-o] Support linker synthesized mach_header symbols.
On darwin in final linked images, the __TEXT segment covers that start of the
file. That means in memory a process can see the mach_header (and load commands)
for every loaded image in a process. There are APIs that take and return the
mach_header addresses as a way to specify a particular loaded image.
For completeness, any code can get the address of the mach_header of the image
it is in by using &__dso_handle. In addition there are mach-o type specific
symbols like __mh_execute_header.
The linker needs to supply a definition for any of these symbols if used. But
the address the symbol it resolves to is not in any section. Instead it is the
address of the start of the __TEXT segment.
I needed to make a small change to SimpleFileNode to not override
resetNextIndex() because the Driver creates a SimpleFileNode to hold the
internal/implicit files that the context/writer can create. For some reason
SimpleFileNode overrode resetNextIndex() to do nothing instead of reseting
the index (which mach-o needs if the internal file is an archive).

This patch enables the vec_vsx_ld and vec_vsx_st intrinsics for
PowerPC, which provide programmer access to the lxvd2x, lxvw4x,
stxvd2x, and stxvw4x instructions.
New LLVM intrinsics are provided to represent these four instructions
in IntrinsicsPowerPC.td. These are patterned after the similar
intrinsics for lvx and stvx (Altivec). In PPCInstrVSX.td, these
intrinsics are tied to the code gen patterns, with additional patterns
to allow plain vanilla loads and stores to still generate these
instructions.
At -O1 and higher the intrinsics are immediately converted to loads
and stores in InstCombineCalls.cpp. This will open up more
optimization opportunities while still allowing the correct
instructions to be generated. (Similar code exists for aligned
Altivec loads and stores.)
The new intrinsics are added to the code that checks for consecutive
loads and stores in PPCISelLowering.cpp, as well as to
PPCTargetLowering::getTgtMemIntrinsic().
There's a new test to verify the correct instructions are generated.
The loads and stores tend to be reordered, so the test just counts
their number. It runs at -O2, as it's not very effective to test this
at -O0, when many unnecessary loads and stores are generated.
I ended up having to modify vsx-fma-m.ll. It turns out this test case
is slightly unreliable, but I don't know a good way to prevent
problems with it. The xvmaddmdp instructions read and write the same
register, which is one of the multiplicands. Commutativity allows
either to be chosen. If the FMAs are reordered differently than
expected by the test, the register assignment can be different as a
result. Hopefully this doesn't change often.

Ensure function_refs are copyable even from non-const references
A subtle bug was found where attempting to copy a non-const function_ref
lvalue would actually invoke the generic forwarding constructor (as it
was a closer match - being T& rather than the const T& of the implicit
copy constructor). In the particular case this lead to a dangling
function_ref member (since it had referenced the function_ref passed by
value to its ctor, rather than the outer function_ref that was still
alive)
SFINAE the converting constructor to not be considered if the copy
constructor is available and demonstrate that this causes the copy to
refer to the original functor, not to the function_ref it was copied
from. (without the code change, the test would fail as Y would be
referencing X and Y() would see the result of the mutation to X, ie: 2)

With this patch MCDisassembler::getInstruction takes an ArrayRef<uint8_t>

Even on X86 there is a maximum size an instruction can have. Given

Extend intrinsic name mangling to support arrays, named structs, and function types.
Currently, we have a type parameter mechanism for intrinsics. Rather than having to specify a separate intrinsic for each combination of argument and return types, we can specify a single intrinsic with one or more type parameters. These type parameters are passed explicitly to Intrinsic::getDeclaration or can be specified implicitly in the naming of the intrinsic function in an LL file.
Today, the types are limited to integer, floating point, and pointer types. With a goal of supporting symbolic targets for patchpoints and statepoints, this change adds support for function types. The change also includes support for first class aggregate types (named structures and arrays) since these appear in function types we've encountered.

We should probably extend this basic idea to metadata of other forms; in particular, range metadata. We view is that assumes should be considered a "last resort" for when there isn't a more canonical way to represent something.

libLTO: Allow linker to choose context of modules and codegen
Add API for specifying which `LLVMContext` each `lto_module_t` and
`lto_code_gen_t` is in.
In particular, this enables the following flow:
for (auto &File : Files) {
lto_module_t M = lto_module_create_in_local_context(File...);
querySymbols(M);
lto_module_dispose(M);
}
lto_code_gen_t CG = lto_codegen_create_in_local_context();
for (auto &File : FilesToLink) {
lto_module_t M = lto_module_create_in_codegen_context(File..., CG);
lto_codegen_add_module(CG, M);
lto_module_dispose(M);
}
lto_codegen_compile(CG);
lto_codegen_write_merged_modules(CG, ...);
lto_codegen_dispose(CG);
This flow has a few benefits.
- Only one module (two if you count the combined module in the code
generator) is in memory at a time.
- Metadata (and constants) from files that are parsed to query symbols
but not linked into the code generator don't pollute the global
context.
- The first for loop can be parallelized, since each module is in its
own context.
- When the code generator is disposed, the memory from LTO gets freed.
