Another dark corner corner of crosstools appeared, and apparently we didn't enable MOSTLY STATIC linking mode flags for dynamic libraries or objc. This cl addresses that in the legacy fields migrator.

Starlark constructors for tool_path and tool do not allow empty strings for the path field. Therefore the migrator replaces the "" with "NOT_USED". We should ignore this difference when comparing the CToolchains.

And fix an error where we added previously unseen action_names to the dictionary of familiar ACTION_NAMES, so later when we would encounter them, we would treat them as variables, not as string literals
eg
env_set {
action = "a"
}
would translate to
env_set(
actions = [a],
)
which is, obviously wrong.

If toolchain A and B need feature f, but toolchain C doesn't, the generated declaration statement for feature f would be:
if ctx.attr.cpu == 'A.cpu':
f = feature(...)
elif ctx.attr.cpu == "B.cpu" and ctx.attr.compiler == "B.compiler":
f = feature(...)
else:
fail("Unreachable")
This will break the rule implementation in the case of toolchain C because it will reach the fail("Unreachable") although it doesn't need to declare feature f
This cl fixes that

If an action_config's name doesn't appear in the action_names.bzl, eg action-a.b+c, in it's assignments statement we would declare it as:
action_a.b+c_action = action_config( ...
This cl fixes it to create the action_config variable with the +, - and .
It also adds tests for action_config

Having a 'per_object_debug_data' feature enabled is giving the same signal as having supports_fission enabled. This is a safe change because all crosstools that have supports_fission: true have per_object_debug_info disabled, and with the legacy crosstool fields migration we will migrate this feature to be enabled by default for these crosstools.

This ensures that the generated files will be unique in the package and therefore there won't be action conflict.

This cl fixes a bug in the migrator where it didn't pass mentioned flags to c++-nodeps-dynamic-library unconditionally (it only passed them as with feature { feature: 'dynamic_linking_mode' }, which is incorrect, the feature doesn't not apply to nodeps-dynamic-library, only to transitive linking actions.

When renaming legacy_*_flags to default_*_flags, also rename other fields such as requires.
We're intentionally not replacing the implies line, just removing it, because default_*_features are enabled by default, so they don't need to be implied (Implied field is older than enabled field, so there are uses of it where enabled would work just fine. The only semantic difference is that implied features cannot be disabled, whereas enabled can. But since the standard style of writing crosstools seems to prefer enabled, I'm doing the same here.)

Another round of fixes:
* if the toolchain contains legacy_compile_flags or legacy_link_flags, replace the feature with default_compile_flags or default_link_flags. This is to ensure the location of the flags stays intact.
* it fixes the order of compilation flags, the correct order is:
1) compiler_flag
2) compilation_mode_flags.compiler_flag
3) cxx_flag
4) compilation_mode_flags.cxx_flag
* We don't add cxx_flags to assemble and preprocess-assemble actions
* We don't add sysroot to assemble action

Our reasoning:
* it only works with gold
* it was broken for the last 3 months (since unknown commit) (silently did
nothing and nobody complained)
* we see almost zero usage of this option

This change adds cc_toolchain.static_runtime_lib and
cc_toolchain.dynamic_runtime_lib attributes and an incompatible flag that
disables deprecated cc_toolchain.static_runtime_libs and
cc_toolchain.dynamic_runtime_libs.
