The separate header file allows to reuse the MIPS ABI flags structure
constants in other LLVM tools like the llvm-readobj.
No functional changes.

Summary: This will enable the IAS to reject floating point instructions if soft-float is enabled.

Summary:
These ISA's didn't add any instructions so they are almost identical to
Mips32r2 and Mips64r2. Even the ELF e_flags are the same, However the ISA
revision in .MIPS.abiflags is 3 or 5 respectively instead of 2.

Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)
Changes made by clang-tidy with minor tweaks.

Options struct and move the comment to inMips16HardFloat. Use the
fact that we now know whether or not we cared about soft float to
set the libcalls.
Accordingly rename mipsSEUsesSoftFloat to abiUsesSoftFloat and
propagate since it's no longer CPU specific.

Summary:
The cpr1_size field describes the minimum register width to run the program
rather than the size of the registers on the target. MIPS32r6 was acting
as if -mfp64 has been given because it starts off with 64-bit FPU registers.

Summary:
When -mno-odd-spreg is in effect, 32-bit floating point values are not
permitted in odd FPU registers. The option also prohibits 32-bit and 64-bit
floating point comparison results from being written to odd registers.
This option has three purposes:
* It allows support for certain MIPS implementations such as loongson-3a that
do not allow the use of odd registers for single precision arithmetic.
* When using -mfpxx, -mno-odd-spreg is the default and this allows us to
statically check that code is compliant with the O32 FPXX ABI since mtc1/mfc1
instructions to/from odd registers are guaranteed not to appear for any
reason. Once this has been established, the user can then re-enable
-modd-spreg to regain the use of all 32 single-precision registers.
* When using -mfp64 and -mno-odd-spreg together, an O32 extension named
O32 FP64A is used as the ABI. This is intended to provide almost all
functionality of an FR=1 processor but can also be executed on a FR=0 core
with the assistance of a hardware compatibility mode which emulates FR=0
behaviour on an FR=1 processor.
* Added '.module oddspreg' and '.module nooddspreg' each of which update
the .MIPS.abiflags section appropriately
* Moved setFpABI() call inside emitDirectiveModuleFP() so that the caller
doesn't have to remember to do it.
* MipsABIFlags now calculates the flags1 and flags2 member on demand rather
than trying to maintain them in the same format they will be emitted in.
There is one portion of the -mfp64 and -mno-odd-spreg combination that is not
implemented yet. Moves to/from odd-numbered double-precision registers must not
use mtc1. I will fix this in a follow-up.

Summary:
Follow on to r212519 to improve the encapsulation and limit the scope of the enums.
Also merged two very similar parser functions, fixed a bug where ASE's
were not being reported, and marked CPR1's as being 128-bit when MSA is
enabled.
