Remove all non-const iterators from Init classes.  This is another
step toward constifying Inits and ultimately turning them into
FoldingSetNodes.

llvm-svn: 136484

Get rid of all Init members that modify internal state.  This is in
preparation for making references to Inits const.

llvm-svn: 136483

Add a getValues ListInit method to return the sequence of values in
the list.

llvm-svn: 136482

Create a std::string wrapper for use as a DenseMap key.  DenseMap is
not safe in generate with strings, so this wrapper indicates that only
strings guaranteed not to have certain values should be used in the
DenseMap.

Fill in the missing fixed bits and the register operand bits of the instruction
encoding. Refactor the definition to make the mode explicit, which is
consistent with how loads and stores are normally represented and makes
parsing much easier. Add parsing aliases for pseudo-instruction variants.
Update the disassembler for the new representations. Add tests for parsing and
encoding.

Renamed Loaded member to ImportedBy, as it's easier to read.  Added another set to represent the modules a module imports.

screwy things by setting PWD != getcwd(). For example, some developers I know
will use this to control the value in gcc's DW_AT_comp_dir value in debug
output. With this patch, that trick will now work on clang too.

The only other effect of this change is that the static analysis will now
respect $PWD when reporting the directory of the files in its HTML output. I
think that's fine.

working on x86 (at least for trivial testcases); other architectures will
need more work so that they actually emit the appropriate instructions for
orderings stricter than 'monotonic'. (As far as I can tell, the ARM, PPC,
Mips, and Alpha backends need such changes.)

rounding errors.

First off, only depend on the actual MC-ized disassemblers in the
targets, not all of the libraries those in turn depend on.

Second off, only depend on those MC-ized disassemblers for targets we're
building.

This should fix builds of fewer than all targets.

Also tidy up code a bit.

Also make PALIGNR masks to don't match 256-bits, which isn't supported
It's also a step to solve PR10489

DiagnosticErrorTraps can be composed (e.g. a trap inside another trap).

Module*. The offsets have moved into corresponding "Base" fields
within the Module itself, where they will also be helpful for
local->global translation (eventually).

Later passes /are/ using this information when running the register
scavenger.

This fixes the second problem in PR10520.

This hidden llc option runs the machine code verifier after expanding
ARM pseudo-instructions, but before if-conversion.

The machine code verifier is much better at pointing out liveness errors
that can trip up the register scavenger.
