x86inc: Support memory operands in src1 in 3-operand instructions

Particularly in code that makes heavy use of macros it's possible
to end up with 3-operand instructions with a memory operand in src1.
In the case of SSE this works fine due to automatic move insertions,
but in AVX that fails since memory operands are only allowed in src2.

The main purpose of this feature is to minimize the amount of code
changes required to facilitate conversion of existing SSE code to AVX.

Fix typos with codespell tool

This includes fixing convert_method_to_flag so it recognizes "gauss"
parameter properly instead of silently defaulting to bicubic.

checkasm: Correctly parse the seed argument as unsigned

it's outside of the signed range.

lookahead: Keep b_exit_thread under ifbuf.mutex

The lookahead_thread main loop checks b_exit_thread and exits if it is set.
That flag is set by x264_lookahead_delete, which uses ifbuf.mutex to guard accessing it.
However, the read in the while-loop condition of lookahead_thread is not guarded,
and so TSAN sometimes reports a data race.

Makefile: Do not create multiple directories in one go

Remove thread priority tweaking

Back in 2009 when this was added it improved scheduling of lookahead
threads on prevalent operating systems at the time.

According to more recent testing by Intel however, lowering thread
priorities does not improve performance on modern operating systems.
And more importantly, doing so on systems with heterogeneous CPU
topologies may actually result in a severe performance reduction.

Removing this code altogether eliminates the issue with performance
degradation on such systems, while having no noticeable impact on
regular systems with homogeneous CPU topologies.

configure: Always make shared imply PIC

Building a shared library without -fPIC does not make sense. On most
architectures, especially recent ones, doing so will give link-time
errors due to relocations in read-only sections like .text. On some
legacy architectures, including i386, it is allowed by default, but will
warn, and is highly discouraged due to the overheads it adds at library
load time. Most architectures were already listed here as having shared
imply PIC, but not all, such as i386 which ends up with unwanted text
relocations, as well as architectures not known to the build system
currently like RISC-V, which does not permit text relocations by
default. There is no good reason to want shared without PIC on any
architecture, so just remove the architecture list.

x86inc: Enable 4-operand emulation for variable blend instructions

With legacy encoding the last operand (the index) must be xmm0,
but aside from that emulating non-destructive forms works
the same as any other instruction.

x86inc: Add REPX macro to repeat instructions/operations

When operating on large blocks of data it's common to repeatedly use
an instruction on multiple registers. Using the REPX macro makes it
easy to quickly write dense code to achieve this without having to
explicitly duplicate the same instruction over and over.

For example,

    REPX {paddw x, m4}, m0, m1, m2, m3
    REPX {mova [r0+16*x], m5}, 0, 1, 2, 3

will expand to

    paddw       m0, m4
    paddw       m1, m4
    paddw       m2, m4
    paddw       m3, m4
    mova [r0+16*0], m5
    mova [r0+16*1], m5
    mova [r0+16*2], m5
    mova [r0+16*3], m5
