[X86] Add test cases for missed opportunity to use a byte test instruction instead of an xor with 0 in parity patterns.

If the input to the ctpop fits in 8 bits, we can use the parity
flag from a TEST instruction, but we're currently XORing with 0.

[X86] Use parity flag from byte test/cmp instruction for __builtin_parity when input fits in 8 bits.

If the upper bits of the __builtin_parity idiom are known to be
0 we were previously emitting an xor with 0 to get the parity flag.
But we can use cmp/test instead which may expose opportunities for
load folding or combining an AND.

[lldb] [test] Fix DW_TAG_GNU_call_site-DW_AT_low_pc.s relocation

I have made the DW_FORM_ref4 relative. One could also use relocated
DW_FORM_ref_addr instead.

Tested with:
        echo 'void f(){}'|clang -o 1.o -c -Wall -g -x c -;./bin/clang -o 1 1.o ../llvm-monorepo/lldb/test/Shell/SymbolFile/DWARF/DW_TAG_GNU_call_site-DW_AT_low_pc.s;./bin/lldb --no-lldbinit ./1 -o r -o 'p p' -o exit

[Clang] Remove run-lines which use opt to run -ipconstprop.

ipconstprop is going to get removed and checking opt with specific
passes makes the tests more fragile.

The tests retain the important checks that !callback metadata is created

Recommit "[IPConstProp] Remove and move tests to SCCP."

This reverts commit 59d6e814ce0e7b40b7cc3ab136b9af2ffab9c6f8.

The cause for the revert (3 clang tests running opt -ipconstprop) was
fixed by removing those lines.
