7bdc1cb690 Use sext in fast isel.
Fast isel used to zero extends immediates to 64 bits. This normally goes
unnoticed because the value is truncated to 32 bits for output.

Two cases were it is noticed:

* We fail to use smaller encodings.
* If the original constant was smaller than i32.

In the tests using i1 constants, codegen would change to use -1, which is fine
(and matches what regular isel does) since only the lowest bit is then used.

Instead, this patch then changes the ir to use i8 constants, which looks more
like what clang produces.

a10307bf95 DebugInfo: Reimplement DIRef<>::resolve() using TypedDebugNodeRef<>
Gut `DIRef<>::resolve()`, reimplementing it using
`TypedDebugNodeRef<>::resolve()`.  Use three separate functions rather
than some sort of type traits, since the latter (i.e., mapping `DIScope`
=> `MDScope`) seems heavy-handed.  I don't expect `DIRef<>` to last much
longer in tree anyway.

As a drive-by fix, make `TypedDebugNodeRef<>::resolve()` do the right
thing with `nullptr`.

93d8e23940 [lit] Skip gtest names starting with DISABLED_
The sanitizer test suite uses this idiom to disable a test.  Now that we
actually check if a test ran after invoking it, we see that zero tests
ran, and complain.

Instead, ignore tests starting with DISABLED_ completely. Fixes the
sanitizer test suite failures on Windows.

cf0d94f462 DebugInfo: Drop confusing forwarding API from DILexicalBlockFile
Remove `DILexicalBlockFile::getScope()` (whose last use was removed from
clang in r234245), which illegally returned a `DILexicalBlock` despite
its scope sometimes being an `MDSubprogram`.  Also remove the
`getLineNumber()` and `getColumnNumber()` methods that just forwarded to
`DILexicalBlock`'s versions, since there don't seem to be any callers.

Note that the block of code removed from `DebugInfo.cpp` was actually
dead code, since `isLexicalBlock()` (the previous branch) always returns
true when `isLexicalBlockFile()` returns true.

An earlier (broken and untested) version of this was squashed into
r234222 and reverted in r234225.

0123b6ee73 [lit] Fix running gtest type-parameterized tests on Windows
The '/' character in the test name of a type-parameterized test is not a
path separator, and should not be '\' on Windows. We were passing a test
name to --gtest_filter which found no tests, so the exit code was zero,
indicating a passed test.

This bug has been here since r84387 in 2009, when Jeff Yasskin added the
original lit support for type-paratermized tests. Somewhere along the
line some of the ValueMapTests started failing, but we can fix those
separately.

This reverts commit r234225, reapplying r234222 in spirit.

loosen the `DILexicalBlock` constructor to require a

A few calls are left in for error checking - but I'm commenting those

1ea24954c6 DebugInfo: Remove DIDescriptor::Verify()
Remove `DIDescriptor::Verify()` and the `Verify()`s from subclasses.
They had already been gutted, and just did an `isa<>` check.

In a couple of cases I've temporarily dropped the check entirely, but
subsequent commits are going to disallow conversions to the
`DIDescriptor`s directly from `MDNode`, so the checks will come back in
another form soon enough.

This array-like wrapper adapts `MDTuple` to have elements of `MDTypeRef`

migrate code using `DITypeArray`.  The only use of this is
`MDSubroutineType`'s `getTypeArray()` accessor.

e009b6fd92 DebugInfo: Use MDTypeRef throughout the hierarchy
Use `MDTypeRef` (etc.) in the new debug info hierarchy rather than raw
`Metadata *` pointers.

I rolled in a change to `DIBuilder` that looks unrelated: take `DIType`
instead of `DITypeRef` as type arguments when creating variables.
However, this was the simplest way to use `MDTypeRef` within the
functions, and didn't require any cleanups from callers in clang (since
they were all passing in `DIType`s anyway, relying on their implicit
conversions to `DITypeRef`).

8af3f965e0 ARM: do not relax Thumb1 -> Thumb2 if only Thumb1 is available.
After recognising that a certain narrow instruction might need a relocation to
be represented, we used to unconditionally relax it to a Thumb2 instruction to
permit this. Unfortunately, some CPUs (e.g. v6m) don't even have most Thumb2
instructions, so we end up emitting a completely invalid instruction.

Theoretically, ELF does have relocations for these situations; but they are
fairly unusable with such short ranges and the ABI document even says they're
documented "for completeness". So an error is probably better there too.

2ec7242600 [X86][SSE] Use (V)PINSRB for direct byte insertion in 16i8 buildvector on SSE4.1 targets
This patch allows SSE4.1 targets to use (V)PINSRB to create 16i8 vectors by inserting i8 scalars directly into a XMM register instead of merging pairs of i8 scalars into a i16 and using the SSE2 PINSRW instruction.

This allows folding of byte loads and reduces scalar register usage as well.

7b0e5b8edc [opaque pointer type] The last of the GEP IRBuilder API migrations
There's still lots of callers passing nullptr, of course - some because
they'll never be migrated (InstCombines for bitcasts - well they don't
make any sense when the pointer type is opaque anyway, for example) and
others that will need more engineering to pass Types around.

7368f2145a Mark BumpPtrAllocator::Allocate as returning a noalias pointer.
The GCC attribute is curiously named 'malloc', but I think it's better
to use LLVM terminology for the wrapper macro.
