an MD5 name would add all remaining bytes to the output buffer but
only advance the input by a byte. For valid inputs, MD5 types are

[SimplifyCFG] Run ReduceSwitchRange unconditionally, generalize
Rather than gating on "isSwitchDense" (resulting in necessesarily
sparse lookup tables even when they were generated), always run
this quite cheap transform.
This transform is useful not just for generating tables.
LowerSwitch also wants this: read LowerSwitch.cpp:257.
Be careful to not generate worse code, by introducing a
SubThreshold heuristic.
Instead of just sorting by signed, generalize the finding of the
best base.
And now that it is run unconditionally, do not replicate its
functionality in SwitchToLookupTable (which could use a Sub
when having a hole is smaller, hence the SubThreshold
heuristic located in a single place).
This simplifies SwitchToLookupTable, and fixes
some ugly corner cases due to the use of signed numbers,
such as a table containing i16 32768 and 32769, of which
32769 would be interpreted as -32768, and now the code thinks
the table is size 65536.
(We still use unconditional subtraction when building a single-register mask,
but I think this whole block should go when the more general sparse
map is added, which doesn't leave empty holes in the table.)
And the reason test4 and test5 did not trigger was documented wrong:
it was because they were not considered sufficiently "dense".

INC/DEC is really a special case of a more generic issue. We should also turn leas into add reg/reg or add reg/imm regardless of the slow lea flags.
This also supports LEA64_32 which has 64 bit input registers and 32 bit output registers. So we need to convert the 64 bit inputs to their 32 bit equivalents to check if they are equal to base reg.
One thing to note, the original code preserved the kill flags by adding operands to the new instruction instead of using addReg. But I think tied operands aren't supposed to have the kill flag set. I dropped the kill flags, but I could probably try to preserve it in the add reg/reg case if we think its important. Not sure which operand its supposed to go on for the LEA64_32r instruction due to the super reg implicit uses.

skipping virtual base-class initializers in such constructors, but it wasn't

[GlobalISel][AArch64] Make FP constraint checks consider possible use/def banks
In a few places in getInstrMapping, we check if use/def instructions for the
instruction we're mapping have floating point constraints.
We can improve this check and reduce the number of copies in GISel-compiled code
if we make a couple observations:
- For a def instruction, it only matters if the def instruction must always
output a value stored on a FPR
- For a use instruction, it only matters if the use instruction must always
only take in values stored in FPRs
This adds two new functions:
- onlyUsesFP
- onlyDefinesFP
Then we can use those when we're checking the uses/defs instead.
Without this patch, the load, unmerge, store, and select in the added test
would have unnecessary copies.

[WebAssembly] Relax signature checking for undefined functions that are not called directly
When function signatures don't match and the undefined function is not
called directly (i.e. only has its address taken) we don't issue a
warning or create a runtime thunk for the undefined function.
Instead in this case we simply use the defined version of the function.
This is possible since checking signatures of dynamic calls happens
at runtime so any invalid usage will still result in a runtime error.
This is needed to allow C++ programs to link without generating
warnings. Its not uncommon in C++ for vtables to be populated by
function address whee the signature of the function is not known in the
compilation unit. In this case clang declares the method as void(void)
and relies on the vtable caller casting the data back to the correct
signature.

Cleanup fixed form sizes.
The fix form sizes use to have two arrays: one for 4 byte addresses and in for 8 byte addresses. The table had an issue where DW_FORM_flag_present wasn't being represented as a fixed size form because its actual size _is_ zero and zero was used to indicate the form isn't fixed in size. Any code that needed to quickly access the DWARF had to get a FixedFormSizes instance using the address byte size.
This fix cleans things up by adding a DWARFFormValue::GetFixedSize() both as a static method and as a member function on DWARFFormValue. It correctly can indicate if a form size is zero. This cleanup is a precursor to a follow up patch where I hope to speed up DWARF parsing.
I verified performance doesn't regress by loading hundreds of DWARF files and setting a breakpoint by file and line and by name in files that do not have DWARF indexes. Performance remained consistent between the two approaches.

[GlobalISel][AArch64] Improve register bank mappings for G_SELECT
The fcsel and csel instructions differ in only the register banks they work on.
So, they're entirely interchangeable otherwise.
With this in mind, this does two things:
- Teach AArch64RegisterBankInfo to consider the inputs to G_SELECT as well as
the outputs.
- Teach it to choose the best register bank mapping based off the constraints
of the inputs and outputs.
The "best" in this case means the one that requires the smallest number of
copies to properly emit a fcsel/csel.
For example, if the inputs are all already going to be on FPRs, we should
emit a fcsel, even if the output is a GPR. This costs one copy to produce the
result, but saves us from copying the inputs into GPRs.
Also update the regbank-select.mir to check that we end up with the right
select instruction.
