Enable FoldConstantArithmetic to constant fold bitcasted constant build vectors. These have typically been bitcasted for type legalization purposes.
By extracting the raw constant bit data, performing the constant fold, and then casting the constant bit data back to the (legalized) type, we can perform constant folding on integer types after legalization.
This in particular helps 32-bit targets which need to handle vXi64 build vectors - during legalization the (unsupported) i64 elements are split to create a bitcasted v2Xi32 build vector.
Addresses some regressions in D113192.

This adds a specific unwind plan for AArch64 Linux sigreturn frames.
Previously we assumed that the fp would be valid here but it is not.
https://github.com/torvalds/linux/blob/master/arch/arm64/kernel/vdso/sigreturn.S
On Ubuntu Bionic it happened to point to an old frame info which meant
you got what looked like a correct backtrace. On Focal, the info is
completely invalid. (probably due to some code shuffling in libc)
This adds an UnwindPlan that knows that the sp in a sigreturn frame
points to an rt_sigframe from which we can offset to get saved
sp and pc values to backtrace correctly.
Based on LibUnwind's change: https://reviews.llvm.org/D90898
A new test is added that sets all compares the frames from the initial
signal catch to the handler break. Ensuring that the stack/frame pointer,
function name and register values match.
(this test is AArch64 Linux specific because it's the only one
with a specific unwind plan for this situation)

Some header `#include`s that belong in TypeConverter.h rather than in
CodeGen.cpp are moved accordingly. As TypeConverter.h is currently only
used in CodeGen.cpp, this wouldn't cause any build issues (ultimately,
all the required headers are included). However, this would become a problem
when including TypeConverter.h elsewhere.
Also, from [1], "(...) include all of the header files that you are
using ". This is currently not the case in TypeConverter.h and hence the
`#include`s should be moved.
I've also added missing namespace qualifiers in a few places in
TypeConverter.h

As of D105532, a couple of llvm-readobj options have slightly changed
their spellings. '-file-headers' has become '--file-header', and
'-symbols' has become '--symbols'. A modern llvm-readobj will respond
to those single-dash spellings by trying to parse them as combinations
of single-letter options, so that you get "unknown argument '-f'" for
-file-headers, and "unknown argument '-y'" for the second letter of
-symbols.
extract_symbols.py was still invoking llvm-readobj with those old
single-dash spellings. Changed them to the newly canonical ones, which
as far as I can tell still work on llvm-readobj from before the
change.

The way function gets the induction variable is by judging whether

An orphan section should be placed in the same memory region as its
anchor section if the latter specifies the memory region explicitly.
If there is no explicit assignment for the anchor section in the linker
script, its memory region is selected by matching attributes, and the
same should be done for the orphan section.
Before the patch, some scripts that were handled smoothly in GNU ld
caused an "error: no memory region specified for section" in lld.
