tcg: Add logical simplifications during gvec expand
We handle many of these during integer expansion, and the
rest of them during integer optimization.

accel/translate-all: Convert a void* cast into an unsigned char* cast
Strictly speaking, as far as the standard care, performing pointer
arithmetic on a void* type is ill formed. This is a GNU extension that
allows this. Instead, just use unsigned char* which preserves the same
behavior.

target/mips: Correct the second argument type of cpu_supports_isa()
"insn_flags" bitfield was expanded from 32-bit to 64-bit in commit
f9c9cd63e3. However, this was not reflected on the second argument
of the function cpu_supports_isa(). By chance, this did not create
some wrong behavior, since the left-most halves of all instances of
the second argument are currently all zeros. However, this is still
a bug waiting to happen. Correct this by changing the type of the
second argument to be always 64-bit.

include/fpu/softfloat: Fix compilation with Clang on s390x
Clang v7.0.1 does not like the __int128 variable type for inline
assembly on s390x:

In file included from fpu/softfloat.c:97:
include/fpu/softfloat-macros.h:647:9: error: inline asm error:
This value type register class is not natively supported!
asm("dlgr %0, %1" : "+r"(n) : "r"(d));
^

Disable this code part there now when compiling with Clang, so that
the generic code gets used instead.

configure: Force the C standard to gnu99
Different versions of GCC and Clang use different versions of the C standard.
This repeatedly caused problems already, e.g. with duplicated typedefs:

https://lists.gnu.org/archive/html/qemu-devel/2018-11/msg05829.html

or with for-loop variable initializers:

https://lists.gnu.org/archive/html/qemu-devel/2019-01/msg00237.html

To avoid these problems, we should enforce the C language version to the
same level for all compilers. Since our minimum compiler versions is
GCC v4.8, our best option is "gnu99" for C code right now ("gnu17" is not
available there yet, and "gnu11" is marked as "experimental"), and "gnu++98"
for the few C++ code that we have in the repository.

documentation for I6500 and I6400 (release 1.0).

target/arm: Add array for supported PMU events, generate PMCEID[01]_EL0
This commit doesn't add any supported events, but provides the framework
for adding them. We store the pm_event structs in a simple array, and
provide the mapping from the event numbers to array indexes in the
supported_event_map array. Because the value of PMCEID[01] depends upon
which events are supported at runtime, generate it dynamically.

target/arm: Swap PMU values before/after migrations
Because of the PMU's design, many register accesses have side effects
which are inter-related, meaning that the normal method of saving CP
registers can result in inconsistent state. These side-effects are
largely handled in pmu_op_start/finish functions which can be called
before and after the state is saved/restored. By doing this and adding
raw read/write functions for the affected registers, we avoid
migration-related inconsistencies.

target/arm: Reorganize PMCCNTR accesses
pmccntr_read and pmccntr_write contained duplicate code that was already
being handled by pmccntr_sync. Consolidate the duplicated code into two
functions: pmccntr_op_start and pmccntr_op_finish. Add a companion to
c15_ccnt in CPUARMState so that we can simultaneously save both the
architectural register value and the last underlying cycle count - this
ensures time isn't lost and will also allow us to access the 'old'
architectural register value in order to detect overflows in later
patches.
