AMDGPU/GlobalISel: Remove -new-reg-bank-select option

AMDGPU's -global-isel pipeline that uses AMDGPURegBankSelect and
AMDGPURegBankLegalize, previously -global-isel -new-reg-bank-select,
is now the default -global-isel pipeline.

Remove -new-reg-bank-select option from the compiler.
Remove -new-reg-bank-select from all llvm regression tests.
Edit a couple comments to reference RegBankLegalize instead of
-new-reg-bank-select.

[llvm][Target] Avoid premature Twine .str() materialization (#204836)

Call sites in the AMDGPU and SPIRV parsers and the SystemZ AsmPrinter /
InstrInfo pass `expr.str()` (or `.str().c_str()`) to parameters of type
`const llvm::Twine &`, forcing a throwaway heap std::string that is
immediately rewrapped into a Twine. Drop the materialization and let
Twine accept the concatenation directly.

AMDGPU/GlobalISel: Use AMDGPURegBankSelect + AMDGPURegBankLegalize by default

Change AMDGPU's default -global-isel pipeline to use AMDGPURegBankSelect
and AMDGPURegBankLegalize (previously -global-isel -new-reg-bank-select)
by default instead of RegBankSelect which uses AMDGPURegisterBankInfo.

-global-isel pipeline that used RegBankSelect/AMDGPURegisterBankInfo is
now deprecated, since it could not generate functionally correct code in
some cases involving divergent control flow and phis.

-new-reg-bank-select option does nothing and will be removed in followup
patch.

Delete regbankselect-mui.ll and regbankselect-mui-salu-float.ll, which
existed to compare the -global-isel vs -global-isel -new-reg-bank-select.

Temporarily disable a couple of tests that are missing AMDGPURegBankLegalize
support.

[libc++] Default the allocator argument for most string constructors (#169901)

Allocators are generally very cheap to copy, so avoiding copies by
having separate overloads is not that useful. Defaulting them
significanlty reduces the overload set the compiler has to consider and
simplifies the code, since we can remove some functions in the future.

Closes #87368
