[clang] use getCommonSugar in an assortment of places
For this patch, a simple search was performed for patterns where there are
two types (usually an LHS and an RHS) which are structurally the same, and there
is some result type which is resolved as either one of them (typically LHS for
consistency).

We change those cases to resolve as the common sugared type between those two,
utilizing the new infrastructure created for this purpose.

isuckatcs cd40245f54 [clang-tidy] Fix false positive on ArrayInitIndexExpr inside ProBoundsConstantArrayIndexCheck
Sometimes in the AST we can have an ArraySubscriptExpr,
where the index is an ArrayInitIndexExpr.
ArrayInitIndexExpr is not a constant, so
ProBoundsConstantArrayIndexCheck reports a warning when
it sees such expression. This expression can only be
implicitly generated, and always appears inside an
ArrayInitLoopExpr, so we shouldn't report a warning.

Sockke 2d8e91a5d3 [clang-tidy] Ignore other members in a union if any member of it is initialized in cppcoreguidelines-pro-type-member-init
If a union member is initialized, the other members of the union are still suggested to be initialized in this check.  This patch fixes this behavior.

Carlos Galvez 3fd4213059 [clang-tidy] Do not trigger cppcoreguidelines-avoid-const-or-ref-data-members on lambda captures
Lambdas are implemented as regular classes internally,
and the captured variables end up as members there.
Do not diagnose those - the check should cover only
regular classes and structs.

[clang-tools-extra] Fixed a number of typos
I went over the output of the following mess of a command:

`(ulimit -m 2000000; ulimit -v 2000000; git ls-files -z | parallel --xargs -0 cat | aspell list --mode=none --ignore-case | grep -E '^[A-Za-z][a-z]*$' | sort | uniq -c | sort -n | grep -vE '.{25}' | aspell pipe -W3 | grep : | cut -d' ' -f2 | less)`

and proceeded to spend a few days looking at it to find probable typos
and fixed a few hundred of them in all of the llvm project (note, the
ones I found are not anywhere near all of them, but it seems like a
good start).

In case of a variable with a built-in boolean type, `false` is a better fit to default-initialize it.

Richard 89a1d03e2b [clang-tidy] Organize test files into subdirectories by module (NFC)
Eliminate clutter by reorganizing the Lit test files for clang-tidy:
- Move checkers/<module>-* to checkers/<module>/*.
- Move module specific inputs from Inputs to <module>/Inputs.  Remove
  any module prefix from the file or subdirectory name as they are no
  longer needed.
- Introduce a Lit substitution %clang_tidy_headers for the system
  headers in checkers/Inputs/Headers and use this throughout.  This
  avoids referencing system headers through a relative path to the
  parent directory and makes it clear that these fake system headers are
  shared among all modules.
- Update add_new_check.py to follow the above conventions when creating
  the boiler plate test files for a new check.
- Update Contributing.rst to describe per-module Inputs directory and
  fix link to test source code.
