0d861a24d8 Remove error-prone methods of BinaryRef.
A user shouldn't care about the internal state, and these methods by
their very nature require asserting a predicate on the internal state.
As such, they cannot be used safely without introducing hidden
long-distance dependencies on the manner of construction of the
BinaryRef.

Use writeAsBinary(raw_ostream &) and writeAsHex(raw_ostream &) if you
need to access the data in a binary or hex format.

639adc59f8 Add writeAsBinary(raw_ostream &) method to BinaryRef.
Previously, yaml2coff.cpp had a writeHexData static helper function to
do this, but it is generally useful functionality.

Also, validate hex strings up-front to avoid running having to handle
errors "deep inside" the yaml2obj code (it also gives better diagnostics
than it used to).

normally displays it. With this change llvm-readobj also displays it and we
can check that llvm-mc output is correct according to the standard.

db9dc53871 yaml2obj: add -format=<fmt> to choose input YAML interpretation
See the comment in yaml2obj.cpp for why this is currently needed.
Eventually we can get rid of this, but for now it is needed in order to
make forward progress with adding ELF support, and should be
straightforward to remove later.

Also, preserve the default of COFF, to avoid breaking existing tests.
This policy can easily be changed later though.

9a508ef64a [PATCH] Fix VGATHER* operand constraints
Add earlyclobber constaints to prevent input register being allocated as
the output register because, according to Intel spec [1], "If any pair

instruction results a UD fault."

bcb1ea8ef6 Represent symbols with a SymbolIndex,SectionIndex pair.
With this patch we use the SectionIndex directly, instead of counting the
number of symbol tables. This saves a DenseMap lookup every time we want to
find which symbol a relocation refers to.

Also simplify based on the fact that there is at most one SHT_SYMTAB and one
SHT_DYNSYM.

d7aad34bcb Fix a tblgen subtargetemitter bug, for future Swift support.
This fixes some of the ridiculously complex code for optimizing the
machine model tables that are shared among all processors of a given
target. A9 and Swift both use the "special" feature that maps old
itinerary classes to new machine model defs. They map different
overlapping subsets of instructions, which wasn't handled correctly.

032d62487c PR15662: Optimized debug info produces out of order function parameters
When a function is inlined we lazily construct the variables
representing the function's parameters. After that, we add any remaining
unused parameters.

If the function doesn't use all the parameters, or uses them out of
order, then the DWARF would produce them in that order, producing a
parameter order that doesn't match the source.

This fix causes us to always keep the arg variables at the start of the
variable list & in the original order from the source.
