loop variable has a type containing 'auto', set the declaration to be invalid
(because we couldn't deduce its type) to prevent follow-on errors.

There are situations which can affect the correctness (or at least expectation)
of the gcov output. For instance, if a call to __gcov_flush() occurs within a
block before the execution count is registered and then the program aborts in
some way, then that block will not be marked as executed. This is not normally
what the user expects.
If we move the code that's registering when a block is executed to the
beginning, we can catch these types of situations.

point registers. We will need this register class later when we add
definitions for instructions mfhc1 and mthc1. Also, remove sub-register indices
sub_fpeven and sub_fpodd and use sub_lo and sub_hi instead.

We generally don't warn about extensions involving keywords reserved
for the implementation, so we shouldn't warn here either: the
standard doesn't require it, and it doesn't provide useful information
to the user.

This adds the following as subgroups of -Wgnu: -Wgnu-alignof-expression,
-Wgnu-case-range, -Wgnu-complex-integer, -Wgnu-conditional-omitted-operand,
-Wgnu-empty-initializer, -Wgnu-label-as-value, -Wgnu-local-label,
and -Wgnu-statement-expression,

Update iterator when the SLP vectorizer changes the instructions in the basic
block by restarting the traversal of the basic block.
Patch by Yi Jiang!
Fixes PR 16899.

load/store instructions defined. Previously, we were defining load/store
instructions for each pointer size (32 and 64-bit), but now we need just one
definition.

functions be compiled as mips32, without having to add attributes. This
is useful in certain situations where you don't want to have to edit the
function attributes in the source. For now it's only an option used for
the compiler developers when debugging the mips16 port.

Update testcase to be more careful about checking register
values. While regexes are general goodness for these sorts of
testcases, in this example, the registers are constrained by
the calling convention, so we can and should check their
explicit values.

Adding a new data structure for storing the Replacements generated for a single
translation unit. Structure contains a vector of Replacements as well a field
indicating the main source file of the translation unit. An optional 'Context'
field allows for tools to provide any information they want about the context
the Replacements were generated in. This context is printed, for example, when
detecting conflicts during Replacement deduplication.
YAML serialization for this data structure is implemented in this patch. Tests
are included.

This moves the logic for handling -mfoo -mno-foo from the driver to -cc1. It
also changes -cc1 to apply the options in order, fixing pr16943.
The handling of -mno-mmx -msse is now an explicit special case.
