Support weak symbols by first looking up if there is an externally visible symbol we can find,
and only if that fails using the one in the object file we're loading.

Summary:
Basically all other methods that look up functions by name skip them if they are mere declarations.
Do the same in FindFunctionNamed.

Summary:
When LLVM_USE_SANITIZE_COVERAGE=YES
and one of the sanitizers is used -fsanitize-coverage=3 will be added
to build flag. This will be used to run a coverage-guided fuzzer on various
llvm libraries.

Only pseudos have patterns on them.
Also don't set the asm string for VINTRP_Pseudo. All pseudos should have empty
asm.
This matches what all other multiclasses do.

This defines the SI versions only, so it shouldn't change anything.
There are no changes other than using the new multiclasses, adding missing
mayLoad/mayStore, and formatting fixes.

This patch teaches the Instruction Combiner how to fold a cttz/ctlz followed by
a icmp plus select into a single cttz/ctlz with flag 'is_zero_undef' cleared.
Added test InstCombine/select-cmp-cttz-ctlz.ll.

Sanitizer coverage constructor must run after asan constructor (for each DSO).
Bump constructor priority to guarantee that.

When lowering memcpy, memset or memmove, this assert checks whether the pointer
operands are in an address space < 256 which means "user defined address space"
on X86. However, this notion of "user defined address space" does not exist
for other targets.

LoopRotate wanted to avoid live range interference by looking at the
uses of a Value in the loop latch and seeing if any lied outside of the
loop. We would wrongly perform this operation on Constants.
This fixes PR22337.

divergent formatting issues. This should prevent any format-only diffs
from sneaking into subsequent changes to port TTI to the new pass
manager.

object that manages a single run of this pass.
This was already essentially how it worked. Within the run function, it
would point members at *stack local* allocations that were only live for
a single run. Instead, it seems much cleaner to have a utility object
whose lifetime is clearly bounded by the run of the pass over the
function and can use member variables in a more direct way.
This also makes it easy to plumb the analyses used into it from the pass
and will make it re-usable with the new pass manager.
No functionality changed here, its just a refactoring.

These tests check that the combination of 227110 (cross block query inst) and 227112 (volatile load semantics) work together properly to allow PRE in cases where a loop contains a volatile access.

For ordered, unordered, equal and not-equal tests, packed float and double comparison instructions can be safely commuted without affecting the results. This patch checks the comparison mode of the (v)cmpps + (v)cmppd instructions and commutes the result if it can.

This is especially useful for the UTF8 -> UTF16 direction, since
there is no equivalent of llvm::SmallString<> for wide characters.
This means that anyone who wants a null terminated string is forced
to manually push and pop their own null terminator.
