all the macros from the modules the user has loaded.
These macros are currently imported textually into
the expression's source code, which turns out not to
impose the horrific string processing overhead that
I thought it would, but I still plan to look into
performance improvements.
Also modified TestCModules to test that this works.

Change `clang` to set `-preserve-bc-uselistorder` for the driver options
`-emit-llvm` and `-save-temps`. The former is useful for reproducing
results from `clang` in `opt` or `llc`, while the latter prevents
`-save-temps` from affecting the output. This is part of PR5680.
`-preserve-bc-uselistorder=true` is currently on by default, but a
follow-up commit in LLVM will reverse it.

relocations. We used to do GEP on a pointer to
the result type, which is wrong. We should be doing
GEP on a pointer to char, which allows us to offset
correctly.
This fixes the C modules testcase, so it's no longer
ExpectFail.

This causes badness for GDB which expects to find a definition in any
compile_unit that has an entry for the variable in its pubnames.

We don't need to repeat the template argument. They are not
ambiguous. MIPS is parameterized for ELFT, so we can't do this
for MIPS, though.

I'd added some stuff to this test case without adding the original
source, which makes updating/adding further stuff rather difficult. So
update it first (& it seems in the interim Clang's changed its output
order a bit, so adjust the CHECK lines to account for that - rather than
hand hacking the IR order which just makes it harder to maintain/change
next time)

This patch tries to fix the following MSVC warning.
warning C4661: 'bool
lld:🧝:ELFFile<lld:🧝:ELF32LE>::isCompatible(unsigned
char,unsigned char)' : no suitable definition provided for explicit
template instantiation request

Certain versions of CMake specify /W3 as part of CMAKE_CXX_FLAGS
by default, before you do anything. Appending /W4 to the end of
this and using the Ninja generator results in
cl : Command line warning D9025 : overriding '/W3' with '/W4'.
It is not possible to suppress this since it is a command line
warning and not a compiler warning, so we must fix the command
line to contain only one value for /Wn.

As a follow-up to r234850, add an implicit conversion from
`DISubprogram` to `DIScope` to support Kaleidoscope Ch. 8. This also
reverts that band-aid from r234890.
(/me learns *again* to build Kaleidoscope before commit...)

With commit r219944, InstCombine can now turn a sqrtl into a llvm.fabs.f64.
The call graph edge originally representing the call to sqrtl becomes invalid.
This patch modifies CGPassManager::RefreshCallGraph() to remove the invalid
call graph edge, which can triggers an assert in
CallGraphNode::addCalledFunction().

In this case we don't actually have any branch probability information and
should not assume to have any. LLVM transforms this into:
%and = and i32 %a, 1
%tobool = icmp eq i32 %and, 0
So, in this case, the result of a bitwise and is compared against 0,
but nevertheless, we should not assume to have probability
information.

The ARMv8 ARMARM states that for these instructions in A64 state:
"Unspecified bits in "imm5" are ignored but should be set to zero by an assembler.", (imm4 for INS).
Make the disassembler accept any encoding with these ignored bits set to 1.

This pass will always try to insert llvm.SI.ifbreak intrinsics
in the same block that its conditional value is computed in. This is
a problem when conditions for breaks or continue are computed outside
of the loop, because the llvm.SI.ifbreak intrinsic ends up being inserted
outside of the loop.
This patch fixes this problem by inserting the llvm.SI.ifbreak
intrinsics in the loop header when the condition is computed outside
the loop.

Summary:
Without this check the following case failed:
Skip a SubBlock which is not a MODULE_BLOCK_ID nor a BLOCKINFO_BLOCK_ID
Got to end of file
TheModule would still be == nullptr, and we would subsequentially fail
when materializing the Module (assert at the start of
BitcodeReader::MaterializeModule).
Bug found with AFL.

Some targets (ie. Mips) have additional rules for ordering the relocation
table entries. Allow them to override generic sortRelocs(), which sorts
entries by Offset.
Then override this function for Mips, to emit HI16 and GOT16 relocations
against the local symbol in pair with the corresponding LO16 relocation.

This patch generates a warning for invalid combination of '-mnan' and
'-march' options, it properly sets NaN encoding for a given '-march',
and it passes a proper NaN encoding to the assembler.

TargetRegisterInfo::getRegPressureLimit has a note that it is an old
model that relies on manually entered classes. Using the newer model of
register pressure sets seems more appropriate. We might eventually even
switch to lib/CodeGen/RegisterPressure.cpp, but we should probably do
incremental changes here.
Using the newer model also makes it easier to take regmasks into account
which is necessary to fix llvm.org/PR23143. I am currently also
preparing a patch for that, but would like to do this switch
independently.

The testcase that is included in the patch caused a crash when doing DebugInfoFinder::processModule
on the module due to DCT->getElements() returning nullptr in DebugInfoFinder::processType.
By doing "DCT->getElements()" instead of "DCT->getElements()->operands()" one gets a DIArray
instead of a raw MDTuple. The former has code to handle null as a 0-element array and
therefore avoids the crash.
