[x86] add fake scalar FP logic instructions to ReplaceableInstrs to save some bytes
We can replace "scalar" FP-bitwise-logic with other forms of bitwise-logic instructions.
Scalar SSE/AVX FP-logic instructions only exist in your imagination and/or the bowels of
compilers, but logically equivalent int, float, and double variants of bitwise-logic
instructions are reality in x86, and the float variant may be a shorter instruction
depending on which flavor (SSE or AVX) of vector ISA you have...so just prefer float all

namespace na {

When changing from na::nb to x::y, "Base::Base" will be changed to "nx::ny::Base" and
"Base::" in "Base::Base" will be replaced with "nx::ny::Base" too, which causes
conflict. This conflict should've been detected when adding replacements but was hidden by `addOrMergeReplacement`. We now also detect conflict when adding replacements where conflict must not happen.
The namespace lookup is tricky here, we simply replace "Base::Base()" with "nx::ny::Base()" as a workaround, which compiles but not perfect.

General clean up of Mach-O error handling in llvm-objdump.
To get a good error message for all files that could contain Mach-O
files the code in llvm-objdump needs to use the archive member name
and name of the architecture of a slice of a universal file in those cases
where the error come from a Mach-O file in an archive or a universal file.
Most of this is fixed by moving the call to checkSymbolTable() into
ProcessMachO() and calling it when the operation needs the symbol
table. And then calling the form of report_error() that has the
ArchiveName and ArchitectureName arguments. One other place
needed to call this form of report_error() also with these arguments.
Also changed the code in MachODump.cpp to not use report_fatal_error()
and use report_error() instead to make the code smaller and cleaner. All
cases of this are for errors with the symbol table which should now never
be tripped since checkSymbolTable() should be called first to get a good
error message in these cases.

isInterestingMemoryAccess now supports returning a mask to be applied to
