Simon Dardis 8bdbff37fe [Support][Chrono] Use explicit cast of text output of time values.
rL316419 exposed a platform specific issue where the type of the values
passed to llvm::format could be different to the format string.

Debian unstable for mips uses long long int for std::chrono:duration,
while x86_64 uses long int.

For mips, this resulted in the value being corrupted when rendered to a
string. Address this by explicitly casting the result of the duration_cast
to the type specified in the format string.

Sam McCall fb4a9b7ede Support formatv of TimePoint with strftime-style formats.
Summary:
Support formatv of TimePoint with strftime-style formats.

Extensions for millis/micros/nanos are added.
Inital use case is HH:MM:SS.MMM timestamps in clangd logs.

Kristof Beyls 7a76b315d6 Revert "Make naming in Host.h in line with coding standards."
This reverts r299062, which caused build failures on Windows.
It also reverts the attempts to fix the windows builds in r299064 and r299065.
The introduction of namespace llvm::sys::detail makes MSVC, and seemingly also
mingw, complain about ambiguity with the existing namespace llvm::detail.
E.g.:
C:\b\slave\sanitizer-windows\llvm\include\llvm/Support/MathExtras.h(184): error C2872: 'detail': ambiguous symbol
C:\b\slave\sanitizer-windows\llvm\include\llvm/Support/PointerLikeTypeTraits.h(31): note: could be 'llvm::detail'
C:\b\slave\sanitizer-windows\llvm\include\llvm/Support/Host.h(80): note: or       'llvm::sys::detail'

In r299064 and r299065 I tried to fix these ambiguities, based on the errors
reported in the log files. It seems however that the build stops early when
this kind of error is encountered, and many build-then-fix-iterations on
Windows may be needed to fix this. Therefore reverting r299062 for now to
get the build working again on Windows.

Pavel Labath c1ec4c9187 Attempt to fix MSVC build broken by r294326
MSVC does not think that `char []` can be constexpr. Switch to regular const.

Pavel Labath 24cb6548e5 [Support] Add FormatVariadic support for chrono types
Summary:
The formatter has three knobs:
- the user can choose which time unit to use for formatting (default: whatever is the unit of the input)
- he can choose whether the unit gets displayed (default: yes)
- he can affect the way the number itself is formatted via standard number formatting options (default:default)

Pavel Labath 59838f7ea6 Reapply "Add Chrono.h - std::chrono support header"
This is a resubmission of r284590. The mingw build should be fixed now. The
problem was we were matching time_t with _localtime_64s, which was incorrect on
_USE_32BIT_TIME_T systems. Instead I use localtime_s, which should always
evaluate to the correct function.

Pavel Labath 504f3844ae Revert "Add Chrono.h - std::chrono support header"
This reverts commit r284590 as it fails on the mingw buildbot. I think I know the
fix, but I cannot test it right now. Will reapply when I verify it works ok.

This reverts r284590.

Pavel Labath 13b6a10e7b Add Chrono.h - std::chrono support header
Summary:
std::chrono mostly covers the functionality of llvm::sys::TimeValue and
lldb_private::TimeValue. This header adds a bit of utility functions and
typedefs, which make the usage of the library and porting code from TimeValues
easier.

Rationale:
- TimePoint typedef - precision of system_clock is implementation defined -
  using a well-defined precision helps maintain consistency between platforms,
  makes it interact better with existing TimeValue classes, and avoids cases
  there a time point is implicitly convertible to a specific precision on some
  platforms but not on others.
- system_clock::to_time_t only accepts time_points with the default system
  precision (even though time_t has only second precision on all platforms we
  support). To avoid the need for explicit casts, I have added a toTimeT()
  wrapper function. toTimePoint(time_t) was not strictly necessary, but I have
  added it for symmetry.
