Summary: ASCII case sorting does not help finding imported symbols quickly, and it is common to have e.g. class Foo and function fooFactory exported/imported from the same file.

[X86] Use __builtin_ia32_vec_ext_v4hi and __builtin_ia32_vec_set_v4hi to implement pextrw/pinsertw MMX intrinsics instead of trying to use native IR.

Without this we end up generating code that doesn't use mmx registers and probably doesn't work well with other mmx intrinsics.

[X86] Remove sse41 extract intrinsics. They are not used by clang and are not implemented by the x86 backend.

Summary:
Adds a new public interface routine __esan_report() which can be used to
request profiling results prior to abnormal termination (e.g., for a server
process killed by its parent where the normal exit does not allow for
normal result reporting).

Implements this for the working-set tool.  The cache frag tool is left
unimplemented as it requires missing iteration capabilities.

Adds a new test.

`const` was dropped by r274958, and the lack of `const` makes GCC6
(correctly) complain.

This removes a few fields from the graph builder by making us compute
things (that we'd always compute anyway) more eagerly.

Place the structure data into `cfstring`.  This both isolates the structures to
permit coalescing in the future (by the linker) as well as ensures that it
doesnt get marked as read-only data.  The structures themselves are not
read-only, only the string contents.

llvm-svn: 274956

Drive-by improvement: We would 1) add CSRs, 2) remove callee saved CSRs
and 3) add all CSRs again for the return block.  Just adding CSRs once
obviously gives the same results.

An identity COPY like this:
   %AL = COPY %AL, %EAX<imp-def>
has no semantic effect, but encodes liveness information: Further users
of %EAX only depend on this instruction even though it does not define
the full register.

Replace the COPY with a KILL instruction in those cases to maintain this
liveness information. (This reverts a small part of r238588 but this
time adds a comment explaining why a KILL instruction is useful).

When calling "settings set target.source-map <old-path> <new-path>", make sure that <new-path> exists before accepting it as a remapping.

We had some clients that had added old source paths remappings to their .lldbinit files and they were causing trouble at a later date. This fix should help mitigate these issues.

This way the metadata will be only generated when asserts enabled,
or when -enable-import-metadata specified
