Summary:
Removes references to initialized variable from the following completions:
int x = ^;
Handles only the trivial cases where the variable name is completed
immediately at the start of initializer or assignment, more complicated
cases aren't covered, e.g. these completions still contain 'x':
// More complicated expressions.
int x = foo(^);
int x = 10 + ^;
// Other kinds of initialization.
int x{^};
int x(^);
// Constructor initializers.
struct Foo {
Foo() : x(^) {}
int x;
};
We should address those in the future, but they are outside of the scope of
this initial change.

Set `LiveReg::PhysReg` to zero when freeing a register instead of
removing it from the entry from `LiveRegMap`. This way no iterators get
invalidated and we can avoid passing around and updating iterators all
over the place.
This does not change any allocator decisions. It is not completely NFC
because the arbitrary iteration order through `LiveRegMap` in
`spillAll()` changes so we may get a different order in those spill
sequences (the amount of spills does not change).
This is in preparation of https://reviews.llvm.org/D52010.

Summary:
This change updates the version number for FDR logs to 5, and update the
trace processing to support changes in the custom event records.
In the runtime, since we're already writing down the record preamble to
handle CPU migrations and TSC wraparound, we can use the same TSC delta
encoding in the custom event and typed event records that we use in
function event records. We do the same change to typed events (which
were unsupported before this change in the trace processing) which now
show up in the trace.
Future changes should increase our testing coverage to make custom and
typed events as first class entities in the FDR mode log processing
tools.
This change is also a good example of how we end up supporting new
record types in the FDR mode implementation. This shows the places where
new record types are added and supported.
Depends on D54139.

As shown, this is used to eliminate redundant code in InstCombine,

we're currently unintentionally dropping flags.

Summary:
LLVM puts output binaries in
`${CMAKE_CURRENT_BINARY_DIR}/${CMAKE_CFG_INTDIR}/bin`. This chunk of
code left out the `${CMAKE_CFG_INTDIR}`. Ultimately, the code signing target
does not need a working directory anyways, so it's safe to just remove it.

Sink Windows version detection code from WindowsSupport.h to Path.inc.
These functions don't need to be inlined. I randomly picked Process.inc
for the Windows version helpers, since that's the most related file.
Sink MakeErrMsg to Program.inc since it's the main client.
Move those functions into the llvm namespace, and delete the scoped
handle copy and assignment operators.

Some weak external symbols were added to the profile runtime in D49953,

Instead of iterating over the leaves to find repeated substrings, and walking
collecting leaf children when we don't necessarily need them, let's just
calculate what we need and iterate over that.
By doing this, we don't have to save every leaf. It's easier to read the code
too and understand what's going on.
The goal here, at the end of the day, is to set up to allow us to do something
like
for (RepeatedSubstring &RS : ST) {
... do stuff with RS ...
}
Which would let us perform the cost model stuff and the repeated substring
query at the same time.

Summary:
The NotEligibleToImport flag on the GlobalValueSummary was set if it
isn't legal to import (e.g. because it references unpromotable locals)
and when it can't be inlined (in which case importing is pointless).
I split out the inlinable piece into a separate flag on the
FunctionSummary (doesn't make sense for aliases or global variables),
because in the future we may want to import for reasons other than
inlining.
