[SampleProfile] Switch getNameTable() to return iterator_range (NFC) (#200995)
This patch teaches SampleProfileReader::getNameTable() to return an
iterator_range instead of a pointer to std::vector<FunctionId>.
This patch is meant to be a preparation patch for the following
speed-up opportunity. I'm planning to lazy-load SecNameTable in a
subsequent patch for performance reasons. We have SecNameTable that
takes up about 90MB on disk. We eager-load this section into
std::vector<FunctionId> on the heap. This ends up taking about 180MB
on the heap because the element type of the section is 8-byte MD5 hash
value while FunctionId takes up 16 bytes. This eager loading shows up
on the execution profile -- about 1%. Since we do have a few places
where we scan the entire NameTable, we should accommodate those places
with iterators that lazy-load SecNameTable.

[LoopFusion] Simplify the logic of checking trip count equality (NFCI). (#201446)
Currently `haveIdenticalTripCounts` has a clunky return value, which
makes it very easy to make a mistake. The returned pair doesn't provide
much value and can be replaced with an optional integer. Also the
function `haveIdenticalTripCounts` does more than what its name
suggests. It checks whether peeling is supported for the pair of loops
or not. Interestingly this is not the only place where we check whether
peeling for this pair is supported!
This patch changes the function and renames it to
`calculateTripCountDiff`. It does exactly what the names says. It tries
to calculate the difference of the trip counts of the two loops and if
it fails it returns an empty optional. It is up to the caller to decide
whether it wants to do fusion/peeling based on this result. The patch
changes some debug output but no functional change is intended.
Datatypes has been modified with explicit specification of size and
signedness to avoid any bug due to overflow in subtraction or comparison
of different integer types.
kconfig: Fix repeated include selftest expectation
The err_repeated_inc test was added with an expected stderr fixture
that does not match the diagnostic printed by kconfig.
Running "make testconfig" currently fails in that test even though the
parser reports the duplicated include correctly:
[stderr]
Kconfig.inc1:4: error: repeated inclusion of Kconfig.inc3
Kconfig.inc2:3: note: location of first inclusion of Kconfig.inc3
The fixture expects "Repeated" and "Location" with capital letters, but
the diagnostic emitted by scripts/kconfig/util.c uses lowercase words.
Update the fixture to match the real message.
Fixes: 102d712ded3e ("kconfig: Error out on duplicated kconfig inclusion")

[RISCV][TargetLowering][P-ext] Support sext_inreg or v2i32/v4i16 vectors on RV32. (#201752)
Update sext_vector_inreg expansion to use sext_inreg. Previously it
emitted 2 shifts that wouldn't be combined.
[SelectionDAG] Fold extracts of subvector inserts
Fold extract_subvector(insert_subvector(...)) when the extraction is
outside the inserted subvector or the inserted subvector only amends
the extracted
In particular,
1. vA extract_subvector (vB insert_subvector(vB X, vC Y, C1), C2) =>
vA extract_subvector(X, C2) when [C2, C2 + A) intersect [C1, C1 + C)
is the empty set
2. ... => extract_subvector(Y, C2 - C1) if [C2, C2 + Y) is a subset of
[C1, C1 + C) - an existing simplification
3. ... => vA insert_subvector(vA extract_subvector(vB X, C2), vC Y, C1 - C2)
if [C1, C1 + C) is a subset of [C2, C2 + A) - that is, if you're only
updating the extracted sub-part.
Adds a regresssion tests for an infinite SelectionDAG cycle that is
fixed by a stack of commits that ends with this one.

These functions are far too simple to make wrapping worthwhile, so
instead we just lift the important shared bit - the value->string
