[X86] Teach X86MCodeEmitter to properly encode zmm16-zmm31 as index
register to vgatherpf/vscatterpf.
We need to encode bit 4 into the EVEX.V' bit. We do this right for
regular gather/scatter which use either MRMSrcMem or MRMDestMem formats.
The prefetches use MRM*m formats.
Fixes an issue recently added to PR36202.

[lldb-server/android] Show more processes by relaxing some checks
By default `platform process list` only shows the processes of the
current user that lldb-server can parse. There are several problems:
- apk programs don't have an executable file. They instead use a package
name as identifier. We should show them instead.
- each apk also runs under a different user. That's how android works
- because of the user permission, some files like
/proc/<pid>/{environ,exe} can't be read.
This results in a very small process list.
This is a local run on my machine
```
(lldb) platform process list 2 matching processes were found on
"remote-android" PID    PARENT USER       TRIPLE                   NAME
====== ====== ========== ========================
============================ 23291  3177            
aarch64-unknown-linux-android sh 23301  23291          
aarch64-unknown-linux-android lldb-server
``` However, I have 700 processes running at this time.
By implementing a few fallbacks for android, I've expanded this list to
202, filtering out kernel processes, which would presumably appear in
this list if the device was rooted.

Something to notice is that the architecture is unkonwn for all apks.
And that's fine, because run-as would be required to gather this
information and that would make this entire functionality massively
slow.
There are still several improvements to make here, like displaying
actual user names, which I'll try to do in a following diff.
Note: Regarding overall apk debugging support from lldb. I'm planning on
having lldb spawn lldb-server by itself with the correct user, so that
everything works well. The initial lldb-server used for connecting to
the remote platform can be reused for such purpose. Furthermore,
eventually lldb could also launch that initial lldb-server on its own.

[WebAssembly] Trapping fptoint builtins and intrinsics
Summary: The WebAssembly backend lowers fptoint instructions to a code
sequence that checks for overflow to avoid traps because fptoint is
supposed to be speculatable. These new builtins and intrinsics give
users a way to depend on the trapping semantics of the underlying
instructions and avoid the extra code generated normally.
Patch by coffee and tlively.

[RISCV] Support fast calling convention
LLVM may annotate the function with fastcc if there has only one caller
and there're no other caller out of the module and the function is not
naked or contain variable arguments.
The fastcc functions could pass the arguments by the caller saved
registers.
