I noticed while working on zero-idiom + dependency-breaking support (PR36671) that most of our binary instruction tests were reusing the same src registers, which would cause the tests to fail once we enable scalar zero-idiom support on btver2. Fixed in all targets to keep them in sync.

This is a fix for the problem arising in D47374 (PR37678):
https://bugs.llvm.org/show_bug.cgi?id=37678
We may not have throughput info because it's not specified in the model
or it's not available with variant scheduling, so assume that those
instructions can execute/complete at max-issue-width.

Summary:
It's super irritating.
[properly configured] git client then complains about that double-newline,
and you have to use `--force` to ignore the warning, since even if you
fix it manually, it will be reintroduced the very next runtime :/

Summary:
{FLDL2E, FLDL2T, FLDLG2, FLDLN2, FLDPI} were using WriteMicrocoded.
- I've measured the values for Broadwell, Haswell, SandyBridge, Skylake.
- For ZnVer1 and Atom, values were transferred form InstRWs.
- For SLM and BtVer2, I've guessed some values :(

Summary:
- I've measured the values for Broadwell, Haswell, SandyBridge, Skylake.
- For ZnVer1 and Atom, values were transferred form `InstRW`s.
- For SLM and BtVer2, values are from Agner.

MOVNTPD/MOVNTPS should be WriteFStore
Standardized BDW/HSW/SKL/SKX WriteFStore/WriteVecStore - fixes some missed instregex patterns. (V)MASKMOVDQU was already using the default, its costs gets increased but is still nowhere near the real cost of that nasty instruction....

WriteFRcp/WriteFRsqrt are split to support scalar, XMM and YMM/ZMM instructions.
WriteFSqrt is split into single/double/long-double sizes and scalar, XMM, YMM and ZMM instructions.
This removes all InstrRW overrides for these instructions.
NOTE: There were a couple of typos in the Znver1 model - notably a 1cy throughput for SQRT that is highly unlikely and doesn't tally with Agner.
NOTE: I had to add Agner's numbers for several targets for WriteFSqrt80.

I intend to add further instruction tests to the resources-x86_64.s test file as required, but this initial commit is to help remove a load of unnecessary InstRW overrides in a future patch

The SandyBridge BMI tests are actually run on IvyBridge as that's the first lowest CPU that actually support the ISAs (but still use the SandyBridge model).

I've copied and regenerated a resource file from btver2 to every x86 scheduler model supported by llvm-mca so we have at least some basic coverage.
For most this has been the avx1 tests, but for silvermont I've used sse42 as thats the latest it supports.
More will be added later.
