This patch adds support for overflow checking when processing
R_AARCH64_CALL26, R_AARCH64_JUMP26, R_AARCH64_CONDBR19,
R_AARCH64_TLSIE_ADR_GOTTPREL_PAGE21, and R_AARCH64_TLSLE_ADD_TPREL_HI12
relocations.

This patch makes the AArch64GotAtomContent, AArch64Plt0AtomContent, and
AArch64PltAtomContent static and also cleanup their formatting.

LLVM can now detect if a fd is seekable on windows.
Original commit message:
Actually check if lseek works instead of using a filename based heuristic.

I can't access my Windows machine at the moment, but the build was breaking with:
c:\b\build\slave\crwinclanglld\build\src\third_party\llvm\tools\lld\lib\readerwriter\elf\mips\MipsTargetLayout.h(38) : error C2440: 'return' : cannot convert from 'lld:🧝:MipsGOTSection<ELFT> *' to 'lld:🧝:AtomSection<ELFT> *'
with
[
ELFT=lld:🧝:Mips32ELType
]
Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
I think this regressed caused in 234727: that the forward-declarations
of MipsGOTSection<> is not enough.

Fill in the TODO in CodeGenPrepare::OptimizeCallInst so that global
variables that are passed to memory intrinsics are aligned in the same
way that allocas are.

Original message.
Have one raw_fd_ostream constructor forward to the other.
This fixes some odd behaviour differences between the two. In particular,
the version that takes a FD no longer unconditionally sets stdout to binary.

Right now MIPS instantiates MipsTargetHandler using Mips32ELType and
Mips64ELType. And in the future we can add a couple more types. That
leads to the large object file size because compiler has to create
copies of MipsTargetHandler and all realted classes for each types used
for instantiation.
The patch introduces two factory functions and puts each of them into
the separate cpp file. That allows to reduce size of single object file.

This reverts commit r234698.
This caused a use-after-free: `QueuedBitPieceExpressions` holds onto
references to `DbgInfoIntrinsic`s and references them past where they're
deleted (this is because the verifier is run as a function pass, and
then `verifyTypeRefs()` is called during `doFinalization()`).
I'll include a reduced crasher for `llc` when I recommit the check.

Summary:
When instruction bundling is enabled and the -mc-relax-all flag is
set, we can write bundle padding directly into fragments and avoid
creating large number of fragments significantly reducing LLVM MC
memory usage.

This will allow the ScopInfo to build the polyhedral representation for
non-affine regions that contain loops. Such loops are basically not visible
in the SCoP representation. Accesses that are variant in such loops are
therefor represented as non-affine accesses.

This will allow the ScopDetection to detect non-affine regions that
contain loops. All loops contained will be collected and are
accessible to later passes in order to adjust the access functions.
As the loops are non-affine and will not be part of the polyhedral
representation later, all accesses that are variant in these loops
have to be over approximated as non-affine accesses. They are
therefore handled the same way as other non-affine accesses.
Additionally, we do not count non-affine loops for the profitability
heuristic, thus a region with only a non-affine loop will only be
detected if the general detection of loop free regions is enabled.

When I fixed these a couple of days ago to iterate over all loops, not just
depth == 1 loops, I inadvertently made it such that we'd only look at the first
top-level loop. Make sure that we really look at all of them.

Summary:
When running the compiler-rt testsuite on FreeBSD (it didn't matter which version), I always got the same error result:

After some investigation, it turns out to be due to the regex used for search test_ symbols in lib/dfsan/scripts/check_customer_wrappers.sh:
grep -E "^\\s*test_.*\(\);" ${DFSAN_CUSTOM_TESTS}
This uses \s to search for whitespace at start of line, but support for \s was only introduced in GNU grep v2.5.4-112-gf979ca0, while both FreeBSD and OSX only have grep 2.5.1 (the last version released under GPLv2).
I propose to change \s into [[:space:]], which is the more portable notation.
Test Plan: Run regression tests, and see that they work now. :)

Clean up a predicate I added in r229731, fix the relevant comment and
add a test case. The earlier version is confusing to read and was also
buggy (probably not a coincidence) till Alexey fixed it in r233881.

Change `MDSubprogram::getFunction()` and
`MDGlobalVariable::getConstant()` to return a `Constant`. Previously,
both returned `ConstantAsMetadata`.
