This patch adds the loop-level heuristics for determining whether branches are more profitable than conditional moves.
These heuristics apply to only inner-most loops.

It turns out we were already allocating static address space for TLS
data along with the non-TLS static data, but this space was going
unused/ignored.
With this change, we include the TLS segment in `__wasm_init_memory`
(which does the work of loading the passive segments into memory when a
module is first loaded). We also set the `__tls_base` global to point
to the start of this segment.
This means that the runtime can use this static copy of the TLS data for
the first/primary thread if it chooses, rather than doing a runtime
allocation prior to calling `__wasm_init_tls`.
Practically speaking, this will allow emscripten to avoid dynamic
allocation of TLS region on the main thread.

A new hidden option -print-on-crash that prints the IR as it was upon entering
the last pass when there is a crash.
The IR is saved in its print form before each pass is started and a
signal handler is registered. If the compilation crashes, the signal
handler will print the saved IR to dbgs(). This option
can be modified using -print-module-scope to get the IR for the complete
module. Note that this option only works with the new pass manager.

Previous patch (https://reviews.llvm.org/D126013) added a new "optimized"

To fix the test failure I decided to remove this attribute.

Currently, llvm-symbolizer doesn't like to parse .debug_info in order to
show the line info for global variables. addr2line does this. In the
future, I'm looking to migrate AddressSanitizer off of internal metadata
over to using debuginfo, and this is predicated on being able to get the
line info for global variables.
This patch adds the requisite support for getting the line info from the
.debug_info section for symbolizing global variables. This only happens
when you ask for a global variable to be symbolized as data.

RAGreedy has two fields of RegisterClassInfo, one called RCI and another RegClassInfo from its base class.
RCI is initialized without freezeReservedRegs first, while RegClassInfo does. Therefore, if reserved registers
information is changed between last time freezeReservedRegs is called and RAGreedy, it's not picked up by RCI.
Instead of having both fields in RAGreedy, remove RCI and use RegClassInfo instead. Also removed is the TRI field
which is present in its base class.

The new test is a copy of the corresponding PS4 test, with the triple
etc updated, because there's currently no good way to make one lit test
"iterate" with multiple targets.
This is essentially a revert of c7ad02009. Indeed, it seems that both
96dbdd75 and c7ad02009 were committed, but c7ad02009 seems to be only
an older version of 96dbdd75's tests.
The tests actually require the target triple to match the host, rather than just having the host in the list of available targets. This change removes `llvm_has_native_target` and instead uses the `native` feature from the lit configuration.

As far as I can tell, the only thing those friend classes access is the
`ValueSP` typedef.
Given that this is a map-ish class, with "Map" in its name, it doesn't
seem like a stretch to make `KeyType`, `ValueType` and `ValueSP` public.
More so when the public methods of the class have `KeyType` and
`ValueSP` arguments and clearly `ValueSP` needs to be accessed from the
outside.
`friend` complicates local reasoning about who can access private
members, which is valuable in a class like this that has every method
locking a mutex to prevent concurrent access.
