For FCMEQ, FCMGE, FCMGT, FCMLE and FCMLT, floating point zero will be
printed as #0.0 instead of #0. To support the history codes using #0,
we consider to let asm parser accept both #0.0 and #0.

Ensure that the tag types are reflected on a replacement. This is particularly
important for the compatibility tag which has multiple representations where the
last definition wins.

This moves the ARM build attributes definitions and support routines into the
Support library. The support routines simply permit the conversion of the value
to and from a string representation.
The movement is prompted in order to permit access to the constants and string
representations from readobj in order to facilitate decoding of the attributes
section.

Tag_nodefaults is even and greater than 32 and thus does not need the special
check to fall into the correct category.

This patch adds two new target-independent calling conventions for runtime
calls - PreserveMost and PreserveAll.
The target-specific implementation for X86-64 is defined as following:
- Arguments are passed as for the default C calling convention
- The same applies for the return value(s)
- PreserveMost preserves all GPRs - except R11
- PreserveAll preserves all GPRs and all XMMs/YMMs - except R11

This is necessary because the classes are shared between all schedulers.
Once this patch series is committed there will be an InstrItinClass for
each mnemonic with minimal grouping. This does increase the size of the
itinerary tables for each MIPS scheduler but we have a few options for dealing
with that later. These options include reducing the number of classes once
we see the best way to simplify them, or by extending tablegen to be able
to compress the table by eliminating duplicates entries, etc.

than it needs to be by 1 bit but I need to finish some other things so
that all the boundary cases will work in that situation. constpool.c
in test-suite will fail to assemble under our new internal test-suite sync
without this change.

MSVC on x64 requires that we create image relative symbol
references to refer to RTTI data. Seeing as how there is no way to
explicitly make reference to a given relocation type in LLVM IR, pattern
match expressions of the form &foo - &__ImageBase.

The GNU as behavior is a bit different and very strange. It will mark any
label that contains an instruction. We can implement that, but using the
type looks more natural since gas will not mark a function if a .word is
used to output the instructions!
