  [flang] Add --gcc-toolchain and --gcc-install-dir options to flang. (#87360)

The `--gcc-toolchain` and `--gcc-install-dir` option were previously only visible to the Clang driver, but not Flang. These determine which assembler, linker, and libraries to use, e.g. for cross-compiling, and therefore are relevant for Flang as well.

Tests are implemented using a mock GCC installation in `basic_cross_linux_tree` copied over from Clang's tests. The Clang driver already contains tests with `--driver-mode=flang` but `flang-new` is an entirely different executable (containing the `-fc1` stage) that should be tested as well. While not all files in `basic_cross_linux_tree` are strictly needed for testing those two driver flags, they will be necessarily needed for future added flags such as `--rtlib`.
 
Also remove the entry `*.o` in flang's `.gitignore` since `crt*.o` files are needed in the GCC mock installation.

Fixes #86729

  [bazel] Add support for building lldb (#87589)

This adds build configuration for building LLDB on macOS and Linux. It
uses a default subset of features that should work out of the box with
macOS + Ubuntu. It is notably missing python support right now, although
some of the scaffolding is there, because of the complexity of linking a
python dylib, especially if you plan to distribute the resulting
liblldb.so.

Most of this build file is pretty simple, one of the unfortunate
patterns I had to use was to split the header and sources cc_library
targets to break circular dependencies.

  [LV, VP]VP intrinsics support for the Loop Vectorizer + adding new tail-folding mode using EVL. (#76172)

This patch introduces generating VP intrinsics in the Loop Vectorizer.

Currently the Loop Vectorizer supports vector predication in a very
limited capacity via tail-folding and masked load/store/gather/scatter
intrinsics. However, this does not let architectures with active vector
length predication support take advantage of their capabilities.
Architectures with general masked predication support also can only take
advantage of predication on memory operations. By having a way for the
Loop Vectorizer to generate Vector Predication intrinsics, which (will)
provide a target-independent way to model predicated vector
instructions. These architectures can make better use of their
predication capabilities.

Our first approach (implemented in this patch) builds on top of the
existing tail-folding mechanism in the LV (just adds a new tail-folding
mode using EVL), but instead of generating masked intrinsics for memory
operations it generates VP intrinsics for loads/stores instructions. The
patch adds a new VPlanTransforms to replace the wide header predicate
compare with EVL and updates codegen for load/stores to use VP
store/load with EVL.

Other important part of this approach is how the Explicit Vector Length
is computed. (VP intrinsics define this vector length parameter as
Explicit Vector Length (EVL)). We use an experimental intrinsic
`get_vector_length`, that can be lowered to architecture specific
instruction(s) to compute EVL.

Also, added a new recipe to emit instructions for computing EVL. Using
VPlan in this way will eventually help build and compare VPlans
corresponding to different strategies and alternatives.
