Automatically detect the appropriate configuration file if RBE=1 is
set to request RBE on all projects, or if DART_RBE=1 is set to request
RBE for Dart only, or otherwise respect the explicit configuration file.
Automatically set the server_address location to the build directory
if it has not already been set. This is unfortunately not supported on
Windows due to the environment variable being set during build but it

To avoid these flags being applied to unexpected build rules, we
separate them out into a separate config that is then pulled in
explicitly in the `dart_precompiled_runtime{,_product}` executable
rules. Only those two executables need the additional empty section:
the product version because it becomes `dartaotruntime` in the SDK
bundle, and the non-product version because some of our tests build
standalone executables using it.
The linker flags were originally removed due to
https://github.com/flutter/flutter/issues/112687.
With the recent removal of bitcode support from Flutter (see
https://github.com/flutter/flutter/issues/107883), I can build
the `ios_release` target locally without any issue.
This also reverts the clang DEPS changes from CL 256208 (again).

To create a Dart standalone executable on MacOS, we modify the
dartaotruntime executable to add the snapshot contents, and the
VM looks into the executable on disk to find the snapshot to load.
Previously, we did this by adding a new 64-bit segment load command
with a single section, where the section's file offset and size
describes the inserted snapshot. This meant the Mach-O header size increased by 152 bytes.
Originally, this wasn't an issue as there was plenty of padding, but
later clang updates removed most of this padding, and so writing the
new header actually overwrote the initial contents of the first section
in the file, which happens to be the __text section. In addition, since
the first section's offset was now declared to be within the header,
utilities that strictly validated the Mach-O format, like codesign,
would report errors.
This CL changes it so that we actually reserve space in the
dartaotruntime header using the -add_empty_section flag to the linker.
In addition, we change from using a segment load command to using a
(40 byte) note load command. This is because a segment load command
specifies that the contents should be loaded in memory, but we don't
use that loaded version. Instead, the VM reloads it from the executable
on disk so it can appropriately mmap the different parts of the
snapshot. A note section instead just declares a section of the
executable as arbitrary data that the owner can read from the file
and use as desired, which is semantically closer to our current usage.
This CL also adds a test to pkg/dartdev/test/commands/compile_test to
ensure that corrupting a random part of the snapshot in the executable
causes signature verification to fail.
This CL also reverts CL 256208, thus relanding the clang changes
starting from June that originally raised awareness of the issue by
greatly reduced the amount of padding after the load commands.

The script attempts to run a subprocess to gather the environment

In case the process fails the environment data will be invalid and
the script will ultimately raise an exception.
This change adds a check for the process failing, and gracefully

Implements a backend targeting RV32GC and RV64GC, based on Linux standardizing around GC. The assembler is written to make it easy to disable usage of C, but because the sizes of some instruction sequences are compile-time constants, an additional build configuration would need to be defined to make use of it.
The assembler and disassembler cover every RV32/64GC instruction. The simulator covers all instructions except accessing CSRs and the floating point state accessible through such, include accrued exceptions and dynamic rounding mode.
Quirks:
- RISC-V is a compare-and-branch architecture, but some existing "architecture-independent" parts of the Dart compiler assume a condition code architecture. To avoid rewriting these parts, we use a peephole in the assembler to map to compare-and-branch. See Assembler::BranchIf. Luckily nothing depended on taking multiple branches on the same condition code set.
- There are no hardware overflow checks, so we must use Hacker's Delight style software checks. Often these are very cheap: if the sign of one operand is known, a single branch is needed.
- The ranges of RISC-V branches and jumps are such that we use 3 levels of generation for forward branches, instead of the 2 levels of near and far branches used on ARM[64]. Nearly all code is handled by the first two levels with 20-bits of range, with enormous regex matchers triggering the third level that uses aupic+jalr to get 32-bits of range.
- For PC-relative calls in AOT, we always generate auipc+jalr pairs with 32-bits of range, so we never generate trampolines.
- Only a subset of registers are available in some compressed instructions, so we assign the most popular uses to these registers. In particular, THR, TMP[2], CODE and PP. This has the effect of assigning CODE and PP to volatile registers in the C calling convention, whereas they are assigned preserved registers on the other architectures. As on ARM64, PP is untagged; this is so short indices can be accessed with a compressed instruction.
- There are no push or pop instructions, so combining pushes and pops is preferred so we can update SP once.
- The C calling convention has a strongly aligned stack, but unlike on ARM64 we don't need to use an alternate stack pointer. The author ensured language was added to the RISC-V psABI making the OS responsible for realigning the stack pointer for signal handlers, allowing Dart to leave the stack pointer misaligned from the C calling convention's point of view until a foreign call.
- We don't bother with the link register tracking done on ARM[64]. Instead we make use of an alternate link register to avoid inline spilling in the write barrier.
Unimplemented:
- non-trivial FFI cases
- Compressed pointers - No intention to implement.
- Unboxed SIMD - We might make use of the V extension registers when the V extension is ratified.
- BigInt intrinsics

This migrates old python2 dict.iteritems() to python3 dict.items().
iteritems was removed in python3 meaning these script will otherwise not
run.
Note that this remains backwards compatible since dict.items() also
existed in python2, though the implementation was more memory intensive
for large dicts (which these likely aren't).
This is similar to https://dart-review.googlesource.com/c/sdk/+/200184

* Migrate to python3; drop python support.
* Update Windows toolchain support.
* Remove some unused methods.
* Python 2.7 is still needed on Windows.
* Update gsutil to a version that supports python3.
