e0c3454771 [docs] Update Target Feature Matrix for the XCore backend.
Disassembler support has recently been added. Fill in some other unknowns
at the same time.

ec8d1a5b72 Extend TableGen instruction selection matcher to improve handling
of complex instruction operands (e.g. address modes).

Currently, if a Pat pattern creates an instruction that has a complex
operand (i.e. one that consists of multiple sub-operands at the MI
level), this operand must match a ComplexPattern DAG pattern with the
correct number of output operands.

This commit extends TableGen to alternatively allow match a complex
operands against multiple separate operands at the DAG level.

This allows using Pat patterns to match pre-increment nodes like
pre_store (which must have separate operands at the DAG level) onto
an instruction pattern that uses a multi-operand memory operand,
like the following example on PowerPC (will be committed as a
follow-on patch):

  def STWU  : DForm_1<37, (outs ptr_rc:$ea_res), (ins GPRC:$rS, memri:$dst),
                    "stwu $rS, $dst", LdStStoreUpd, []>,
                    RegConstraint<"$dst.reg = $ea_res">, NoEncode<"$ea_res">;

  def : Pat<(pre_store GPRC:$rS, ptr_rc:$ptrreg, iaddroff:$ptroff),
            (STWU GPRC:$rS, iaddroff:$ptroff, ptr_rc:$ptrreg)>;

Here, the pair of "ptroff" and "ptrreg" operands is matched onto the
complex operand "dst" of class "memri" in the "STWU" instruction.

Approved by Jakob Stoklund Olesen.

a7aec400a7 docs: Fix long standing linking antipattern.
Before we learned about :doc:, we used :ref: and put a dummy link at the
top of each page. Don't do that anymore.

This fixes PR14891 as a special case.

2d4a477b48 docs: Fix reference to "bold" part of code example.
Fixes PR14380.

The prose was referring to a "bold" part of the code example, where the
boldness was lost in the transition from HTML. Unlike HTML, where one
can easily have a <b> inside a <pre>, reStructuredText is generally
unable to represent such nested markup.

Hack around it with the :emphasise-lines: option to the  code-block
directive to single out the regions instead. Thankfully the regions are
close-enough to being full lines for this to work.
