r259433 introduced a regression, where if a compiler is specified without a path (e.g., CC=clang,

[LVI] Introduce an intersect operation on lattice values
LVI has several separate sources of facts - edge local conditions, recursive queries, assumes, and control independent value facts - which all apply to the same value at the same location. The existing implementation was very conservative about exploiting all of these facts at once.
This change introduces an "intersect" function specifically to abstract the action of picking a good set of facts from all of the separate facts given. At the moment, this function is relatively simple (i.e. mostly just reuses the bits which were already there), but even the minor additions reveal the inherent power. For example, JumpThreading is now capable of doing an inductive proof that a particular value is always positive and removing a half range check.
I'm currently only using the new intersect function in one place. If folks are happy with the direction of the work, I plan on making a series of small changes without review to replace mergeIn with intersect at all the appropriate places.

Use dyn_cast instead of static_cast.
Now that MachoFile has classof(), we can use dyn_cast instead which
is actually the only safe way to handle this.
Turns out this actually manifests as a bug as we were incorrectly
casting instances which weren't MachoFile in to a MachoFile.
Unfortunately, there's no reliable way of checking for this as it
requires that the file we are looking for has a 0 at exactly the byte
we need for the load of subsectionsViaSymbols.

ELF: Teach SymbolBody about how to get its addresses.
Previously, the methods to get symbol addresses were somewhat scattered
in many places. You can use getEntryAddr returns the address of the symbol,
but if you want to get the GOT address for the symbol, you needed to call
Out<ELFT>::Got->getEntryAddr(Sym). This change adds new functions, getVA,
getGotVA, getGotPltVA, and getPltVA to SymbolBody, so that you can use
SymbolBody as the central place to ask about symbols.

Avoid inlining call sites in unreachable-terminated block
Summary:
If the normal destination of the invoke or the parent block of the call site is unreachable-terminated, there is little point in inlining the call site unless there is literally zero cost. Unlike my previous change (D15289), this change specifically handle the call sites followed by unreachable in the same basic block for call or in the normal destination for the invoke. This change could be a reasonable first step to conservatively inline call sites leading to an unreachable-terminated block while BFI / BPI is not yet available in inliner.

- ScalarEvolution::isKnownPredicateViaConstantRanges duplicates some
logic already present in ConstantRange, use ConstantRange for those
bits.
- In some cases ScalarEvolution::isKnownPredicateViaConstantRanges
returns `false` to mean "definitely false" (e.g. see the
`LHSRange.getSignedMin().sge(RHSRange.getSignedMax())` case for
`ICmpInst::ICMP_SLT`), but for `isKnownPredicateViaConstantRanges`,
`false` actually means "don't know". Get rid of this extra bit of

Fix infinite recursion in MCAsmStreamer::EmitValueImpl.
If a target can only emit 8-bits data, we would loop in EmitValueImpl

AArch64: Implement missed conditional compare sequences.
Summary:
This is an extension to the existing implementation of r242436 which
restricts to only select inputs. This version fixes missed opportunities
in pr26084 by attempting to lower conditional compare sequences of
and/or trees with setcc leafs. This will additionaly handle the case
when a tree with select input is not a conjunction-disjunction tree
but some of the sub trees are conjunction-disjunction trees.
