David Green 83bbfaa5e4 [ARM] Put some of the TTI costmodel behind hasNeon calls.
This puts some of the calls in ARMTargetTransformInfo.cpp behind hasNeon()
checks, now that we have MVE, and updates all the tests accordingly.

David Green 84cb4b2b53 [ARM] Add or update a number of costmodel tests. NFC
This adds a number of cost model tests for ARM, useful for MVE. It also re-jigs
some of the existing tests to make them easier to update and read.

Kostya Kortchinsky 8095449e68 [scudo][standalone] Minor corrections
Summary:
Few corrections with no functional change:
- replacing `%zd` with `%zu` all around: the values are unsigned
- prefer `MAP_ANONYMOUS` to `MAP_ANON` (it's deprecated)
- remove the unused `enum LinkerInitialized`
- mark a parameter as `UNUSED` in Fuchsia's `getRandom`
- correct the casing of a variable and use `nullptr` instead of 0 for
  pointers in `list.h`
- reorder some `typedef` to be consistent between `signed` and
  `unsigned`

Convert SymbolNameSize and SectionNameSize into just `NameSize`. The length of
a name embeded in a symbol table entry or section header table entry is length 8
for Sections, Symbols and Files. No need to have a distinct constant for each
one. Also removes the Size argument to 'generateStringRef' as the size is

See https://crbug.com/992871#c3 for how to reproduce.

> Patch https://reviews.llvm.org/D43256 introduced more aggressive loop layout optimization which depends on profile information. If profile information is not available, the statically estimated profile information(generated by BranchProbabilityInfo.cpp) is used. If user program doesn't behave as BranchProbabilityInfo.cpp expected, the layout may be worse.

Summary: It is possible to write include code from other files so that the decls from there do not become topLevelDecls (For example by including methods for a class). These Decls are not filtered by topLevelDecls and therefore SemanticHighlighting must manually check that every SLoc belongs in the main file. Otherwise there can be highlightings appearing in places where they should not.

Eric Fiselier b0945e1bd2 Improve codegen for deque.
This patch rewrites a few loops in deque and split_buffer to better
optimize the codegen. For constructors like
`deque<unsigned char> d(500000, 0);` this patch results in a 2x speedup.

The patch improves the codegen  in roughly three ways:

1. Changes do { ... } while (...) loops into more typical for loops.
  The optimizer can reason about normal looking loops better.

2. Split the iteration over a range into (A) iteration over the blocks,
then (B) iteration within the block. This nested structure helps LLVM
lower the inner loop to `memset`.

3. Do fewer things each iteration. Some of these loops were incrementing
  or changing 4-5 variables every loop (in addition to the
  construction). Previously most loops would increment the end pointer,
  the size, and decrement the count of remaining items to construct.
  Now we only increment a single pointer for most iterations.
