commit f025692c992c ("accel/tcg: Clear PAGE_WRITE before translation") fixed cross-modifying code handling, but did not add a test. The changed code was further improved recently [1], and I was not sure whether these modifications were safe (spoiler: they were fine).
Add a test to make sure there are no regressions.

linux-user/i386: Fix allocation and alignment of fp state
For modern cpus, the kernel uses xsave to store all extra cpu state across the signal handler. For xsave/xrstor to work, the pointer must be 64 byte aligned. Moreover, the regular part of the signal frame must be 16 byte aligned.
Attempt to mirror the kernel code as much as possible. Use enum FPStateKind instead of use_xsave() and use_fxsr().

target/i386: fix cmpxchg with 32-bit register destination
Unlike the memory case, where "the destination operand receives a write cycle without regard to the result of the comparison", rm must not be touched altogether if the write fails, including not zero-extending it on 64-bit processors. This is not how the movcond currently works, because it is always followed by a gen_op_mov_reg_v to rm.
To fix it, introduce a new function that is similar to gen_op_mov_reg_v but writes to a TCG temporary.
Considering that gen_extu(ot, oldv) is not needed in the memory case either, the two cases for register and memory destinations are different enough that one might as well fuse the two "if (mod == 3)" into one. So do that too.

tests/tcg: i386: add MMX and 3DNow! tests
Adjust the test-avx.py generator to produce tests specifically for MMX and 3DNow. Using a separate generator introduces some code duplication, but is a simpler approach because of test-avx's extra complexity to support 3- and 4-operand AVX instructions.
If needed, a common library can be introduced later.
While at it, for consistency move all the -cpu max rules to the same place.

target/i386: Make translator stop before the end of a page
Right now translator stops right *after* the end of a page, which breaks reporting of fault locations when the last instruction of a multi-insn translation block crosses a page boundary.
An implementation, like the one arm and s390x have, would require an i386 length disassembler, which is burdensome to maintain. Another alternative would be to single-step at the end of a guest page, but this may come with a performance impact.
Fix by snapshotting disassembly state and restoring it after we figure out we crossed a page boundary. This includes rolling back cc_op updates and emitted ops.

Results are bit-identical to an Intel i5-8500, with the exception of the RCPSS and RSQRT approximations where the real CPU gives less accurate results (the Intel spec allows relative errors up to 1.5 * 2^-12)
