[clang] [Driver] More flexible rules for loading default configs
Change the default config file loading logic to be more flexible
and more readable at the same time. The new algorithm focuses on four
locations, in order:
1. <triple>-<mode>.cfg using real driver mode
2. <triple>-<mode>.cfg using executable suffix
3. <triple>.cfg + <mode>.cfg using real driver mode
4. <triple>.cfg + <mode>.cfg using executable suffix
This is meant to preserve reasonable level of compatibility with
the existing use, while introducing more flexibility and making the code
simpler. Notably:
1. In this layout, the actual target triple is normally respected,
and e.g. in `-m32` build the `x86_64-*` configs will never be used.
2. Both real driver mode (preferable) and executable suffix are
supported. This permits correctly handling calls with explicit
`--driver-mode=` while at the same time preserving compatibility
with the existing code.
3. The first two locations provide users with the ability to override
configuration per specific target+mode combinaton, while the next two
make it possible to independently specify per-target and per-mode
configuration.
4. All config file locations are applicable independently of whether
clang is started via a prefixed executable, or bare `clang`.
5. If the target is not explicitly specified and the executable prefix
does not name a valid triple, it is used instead of the actual target
triple for backwards compatibility.
This is particularly meant to address Gentoo's use case for
configuration files: to configure the default runtimes (i.e. `-rtlib=`,
`-stdlib=`) and `--gcc-install-dir=` for all the relevant drivers,
as well as to make it more convenient for users to override `-W` flags
to test compatibility with future versions of Clang easier.

When there are variable errors, display an error in VS Code's local variables view.
After recent diffs that enable variable errors that stop variables from being correctly displayed when debugging, allow users to see these errors in the LOCALS variables in the VS Code UI. We do this by detecting when no variables are available and when there is an error to be displayed, and we add a single variable named "<error>" whose value is a string error that the user can read. This allows the user to be aware of the reason variables are not available and fix the issue. Previously if someone enabled "-gline-tables-only" or was debugging with DWARF in .o files or with .dwo files and those separate object files were missing or they were out of date, the user would see nothing in the variables view. Communicating these errors to the user is essential to a good debugging experience.

[DSE] Eliminate noop store even through has clobbering between LoadI and StoreI
For noop store of the form of LoadI and StoreI,
An invariant should be kept is that the memory state of the related
MemoryLoc before LoadI is the same as before StoreI.
For this example:
```
define void @pr49927(i32* %q, i32* %p) {
%v = load i32, i32* %p, align 4
store i32 %v, i32* %q, align 4
store i32 %v, i32* %p, align 4
ret void
}
```
Here the definition of the store's destination is different with the
definition of the load's destination, which it seems that the
invariant mentioned above is broken. But the definition of the
store's destination would write a value that is LoadI, actually, the
invariant is still kept. So we can safely ignore it.

[ModuleInliner] Add a cost-benefit-based priority
This patch teaches the module inliner a traversal order designed for

The new traversal order prioritizes call sites in the following order:
1. Those call sites that are expected to reduce the caller size
2. Those call sites that have gone through the cost-benefit analaysis
3. The remaining call sites
With this fairly simple traversal order, a large internel benchmark
yields performance comparable to the bottom-up inliner -- both in
terms of the execution performance and .text* sizes.
Big thanks goes to Liqiang Tao for the module inliner infrastructure.
