the target's register size we can easily create a bitfield and just
do a simple test for set membership.
int foo(char C) { return strchr("123!", C) != nullptr; } now becomes

The code is currently limited to bit fields that fit in a register, so
usually 64 or 32 bits. Sadly, this misses anything using alpha chars
or {}. This could be fixed by just emitting a i128 bit field, but that
can generate really ugly code so we have to find a better way. To some
degree this is also recreating switch lowering logic, but we can't
simply emit a switch instruction and thus change the CFG within

Fix ComputeSupportExeDirectory for Linux (merge with Android).
Summary:
ComputeSupportExeDirectory relied on ComputeSharedLibraryDirectory which was
not always reliable. Using procfs seems to be the best way to deal with it on
Linux (since it's already done on Android, might as well merge it).

[CodeGen][IfCvt] Don't re-ifcvt blocks with unanalyzable terminators.
If we couldn't analyze its terminator (i.e., it's an indirectbr, or some

because we can't tell whether the predicated terminator can
fallthrough (it does).
Currently, we would completely ignore the fallthrough successor. In
the added testcase, this means we used to generate:

[X86, AVX] instcombine common cases of vperm2* intrinsics into shuffles
vperm2* intrinsics are just shuffles.
In a few special cases, they're not even shuffles.
Optimizing intrinsics in InstCombine is better than
handling this in the front-end for at least two reasons:
1. Optimizing custom-written SSE intrinsic code at -O0 makes vector coders
really angry (and so I have regrets about some patches from last week).
2. Doing mask conversion logic in header files is hard to write and
subsequently read.
There are a couple of TODOs in this patch to complete this optimization.

DebugInfo: Require valid DIDescriptors
As part of PR22777, switch from `dyn_cast_or_null<>` to `cast<>` in most
`DIDescriptor` accessors. These classes are lightweight wrappers around
pointers, so the users should check for valid pointers before using
them.
This survives a Darwin clang -g bootstrap (after fixing testcases), but
it's possible the bots will complain about other configurations. I'll
fix any fallout as quickly as I can! Once this bakes for a bit I'll
remove the macros.
Note that `DebugLoc` implicitly gets stricter with this change as well,
since it forward to `DILocation`. Any code that's using `DebugLoc`
accessors should check `DebugLoc::isUnknown()` first. (BTW, I'm also
partway through a cleanup of the `DebugLoc` API to make it more obvious
what it is (a glorified pointer wrapper) and remove cruft from before
the Metadata/Value split. I'll commit soon.)
