It makes more sense to print out the number of micro opcodes that are issued
every cycle rather than the number of instructions issued per cycle.
This behavior is also consistent with the dispatch-stats: numbers from the two
views can now be easily compared.

Summary:
When calling TUScehduler::runWithPreamble (e.g. in code compleiton), allow
entering a fallback mode when compile command or preamble is not ready, instead of
waiting. This allows clangd to perform naive code completion e.g. using identifiers
in the current file or symbols in the index.

This patch simply returns empty result for code completion in fallback mode. Identifier-based
plus more advanced index-based completion will be added in followup patches.

I was looking at a potential DAGCombiner fix for 1 of the regressions in D60278, and it caused severe regression test pain because x86 TLI lies about the desirability of 8-bit shift ops.

We've hinted at making all 8-bit ops undesirable for the reason in the code comment:

// TODO: Almost no 8-bit ops are desirable because they have no actual
//       size/speed advantages vs. 32-bit ops, but they do have a major
//       potential disadvantage by causing partial register stalls.

...but that leads to massive diffs and exposes all kinds of optimization holes itself.

First step towards removing the MOVMSK intrinsics completely - this patch expands MOVMSK to the pattern:

e.g. PMOVMSKB(v16i8 x):
%cmp = icmp slt <16 x i8> %x, zeroinitializer
%int = bitcast <16 x i8> %cmp to i16
%res = zext i16 %int to i32

Which is correctly handled by ISel and FastIsel (give or take an annoying movzx move....): https://godbolt.org/z/rkrSFW

Summary:
The ModuleList stream consists of an integer giving the number of
entries in the list, followed by the list itself. Each entry in the list
describes a module (dynamically loaded objects which were loaded in the
process when it crashed (or when the minidump was generated).

The code for reading the list is relatively straight-forward, with a
single gotcha. Some minidump writers are emitting padding after the
"count" field in order to align the subsequent list on 8 byte boundary
(this depends on how their ModuleList type was defined and the native
alignment of various types on their platform). Fortunately, the minidump
format contains enough redundancy (in the form of the stream length
field in the stream directory), which allows us to detect this situation
and correct it.

This patch just adds the ability to parse the stream. Code for
conversion to/from yaml will come in a follow-up patch.

wcrtomb is not intercepted on windows, so this test fails there. It's
not clear to me why we do not intercept this function there (I'll look
into that separately), but for now this should at least make the windows
sanitizer bot green again (broken by r357889, when I added this test).

I also add "UNSUPPORTED: android" as this function is also not
intercepted there.

llvm-svn: 357892

There are no patterns like that in the generated swig files (there
probably were some back in the days when we were running swig over the
header files directly), so this is dead code and has no effect on the
generated file.

llvm-svn: 357890

Summary:
r357240 added an interceptor for wctomb, which uses a temporary local
buffer to make sure we don't write to unallocated memory. This patch
applies the same technique to wcrtomb, and adds some additional tests
for this function.

[X86] Make LowerOperationWrapper more robust. Remove now unnecessary ReplaceAllUsesWith from LowerMSCATTER.

Previously LowerOperationWrapper took the number of results from the original
node and counted that many results from the new node. This was intended to drop
chain operands from FP_TO_SINT lowering that uses X87 with memory operations to
stack temporaries. The final load had an extra chain output that needs to be
ignored.

Unfortunately, it didn't work with scatter which has 2 result operands, the
mask output which is discarded and a chain output. The chain output is the one
that is needed but it comes second and it would be dropped by the previous
logic here. To workaround this we were doing a ReplaceAllUses in the lowering
code so that the generic legalization code wouldn't see any uses to replace
since it had been given the wrong result/type.

After this change we take the LowerOperation result directly if the original
node has one result. This allows us to directly return the chain from scatter
or the load data from the FP_TO_SINT case. When the original node has multiple
results we'll ensure the returned node has the same number and copy them over.
For cases where the original node has multiple results and the new code for some
reason has even more results, MERGE_VALUES can be used to pass only the needed
results.

Previously, we drop symbols starting with .L from the symbol table, so
if there is a relocation that refers a .L symbol, it ended up
referencing a null -- which happened to be interpreted as an absolute
symbol.

This patch copies all symbols including local ones if -emit-reloc is
given.
