ARM: Correct alignment of structs passed as byval pointer
...
When a struct has bitfields overlapping with other members
(as required by the AAPCS), clang uses a packed struct to
represent this. If such a struct is large enough for clang to
pass it as a byval pointer (>64 bytes), we need to set the
alignment of the argument to match the original type.

Normalise the path separator character on non-windows platforms. Although this

full UNC paths. This change enables the use of the Windows SDK on Linux which
will not accept '\' as a path separator.

Like the binary operator check of r201702, this actually checks the
condition of every if in a chain against every other condition, an
O(N^2) operation. In most cases N should be small enough to make this

to catch a copy-paste error within the same series of branches.

Fix recent regressions in -Wreturn-type caused by heuristics to -Wunreachable-code.
...
I had forgotten that the same reachability code is used by both -Wreturn-type
and -Wunreachable-code, so the heuristics applied to the latter were indirectly
impacting the former.
To address this, the reachability code is more refactored so that whiled
the logic at its core is shared, the intention of the clients are better
captured and segregated in helper APIs.
Fixes PR19074, and also some false positives reported offline to me
by Nick Lewycky.
